I have to say that I think the sibling theory is possible. It is a lot more possible than Lily-Lupin or Lily-anyone else or James-McGonagall or James-anyone else. They were in love, everyone says so. Some of you have very sick minds!


QUOTE
I htink the most believable are either Lily and Lupin or Jaames and McGonnagal. Lily loves Lupin.Lupin loves Lily. But Lupin says no because he is a werewolf. They have sex and Hermione is produced. Lily then has to convince James Hermione is his. James is PIG HEAD! He is a bully like his son and I believe He may have made McGonnagal pregnant. Through rape?


Jo would never put that in a children's book!!

Hmm.. Interesting...

this is an interesting theory. I've never considered that possibility. There are alot of great points you mentioned that I never saw before.

I don't think it will happen, but it won't be a total shock if it happens, but I think it is really to Star Wars-ish.

i personaly think that they will eventually be siblings. i think harry will marry Ginny, and Hermione will marry ron, so the trio will be siblings by marriage!

But seriously, great theory, it's really well thought out!

wow! that was a lot to read! i totally NEVER thought of any of that! but i saw the topic title and i knew that it would be interesting and i just HAD to read it! there was so much stuff that i had just read over without thinking anything of it!

this is an awesome theory! i can totally picture this happening now! i mean, its totally possible! and i definitley think that hermione would be the one to know....she has proved herself very capable of keeping secrets from her close friends. and dumbledore has kept things from harry before, we found that out in his whole explanation after Sirius's death. and if Harry were to know, i think that he would probably do something irrational. he'd probably be really happy that he has another family member that he can turn to, but at the same time, he'd probably be like "why wasn't i ever told?!!!"! i think that it would totally bring a new scandal to the book. i really wouldn't underestimate JKR's power to do something like this. it would totally throw a curveball at all of us......

Hi, I haven't read every single reply to the theory but I've read a few and I have to make some comments. Firstly, I was totally up for this theory with the exception that I disagreed with only a few interpetations of lines, quotes, etc. However, it dawned on me one very key importance just last night. I'm reading book 1 again via audio tape and in the beginning, Uncle Vernon mentions or well, via narrator it's put to words that he knows about "The Potters" and their son. Now if he knew about Harry, why wouldn't it be mentioned that he knew about their "daughter" as well? He's a completely neutral source who wouldn't have been told to keep it shushed up if James and Lily had Hermione. It was his own thoughts so to speak and he's free to think them. Besides, they never even mentioned Harry, why be afraid if he knew about Hermione?

Lastly, I like the idea of Lupin being her father but it was said in an interview with JK that Lupin did have feelings for Lily but that he would never act on them because of his friendship for James. That he wouldn't want it to come between them. I think he fell in love with Lily, much like Snape, but out of respect for James, never acted on it. However in the scene of POA you can tell he's very in love with her and JK herself has said that the director added and picked up on key elements that would be important later on. Maybe the Lupin/Lily relationship is important.

Also, Lupin was dead set against being with Tonks. I think it's cause he's afraid of the werewolf part of him naturally and would that transfer to his children? If Lupin is a werewolf, wouldn't he be afraid to pass on that trait? He seems the type to be concerned about such things and if Lily was able to convince him to not worry about this, then she would have had to of been deeply in love with him to over look it but yet she married James?

And I agree with the people that say that if Hermione was indeed Harry's sister/half sister, then Sirius and Remus and even Peter would have acted more intersted in her. As it is, they only ask about her (Lupin/Sirius) the way they ask about Ron.

I would love for it to happen, I really would. I've always wanted Hermione to have some form of importance in Harry's life, something more substantial than just a friend. I know it's clear she's with Ron and that's adorable but it annoys me how they team up against her sometimes. Sure they take up for her but in book 4 even though Hermione took up for Harry and stood by him, he kept pining for Ron and thinking about how boring it was being Hermione's best friend. Anyway, I'm anxious for the seventh book. So many good theories, I can't wait to see who was right!

For those who think the theory is plausible, or who just want to read more, ther eis a link to Sibling Theory fan fiction in my signature. I think it's most likely that Hermione's Lupin and Lily's daughter. There are many clues supporting that - for example, in POA, it says "the werewolf only responds t othe call of its own kind" then Hermione howls and Lupin reacts...hmm...

No Starliteprism, we all get those tiny footprints. Weird, huh? Well I was totally up for this theory upon first glance but now, I have to say I can't find cause in it. I think some of the evidence was read into too deeply. Some things said are to be taken at face value only. I'm sure JK must get a kick out of lots of us who think something is a clue and we analyze it to death and she's thinking "It was just a phrase! Nothing more!" But hey, we can all dream, right? I applaud the research gone into this theory and am not poking fun. However I see too many holes in it. Too many people would know of Hermione's existance to not blab about it earlier. Ie Peter Pettigrew of course. She would only been like what? 10 months older than Harry? Why would they deny her existance so early on? And I don't see Lily having an affair, I really don't. Especially with Lupin. I think he would be too afraid of having a child with his werewolf problem. I know JK has said about movie 3 that the director picked up on things that would be super important later on and that he didn't realize he was doing it at the time. I think one of the key things he picked up on was Lupin's feelings for Lily as it wasn't so evident in the book itself. I know a lot of people walked away from that movie thinking "Wow, sounds like Remus was in love." just from that one scene with Harry. But I do believe that JK has said he wouldn't have acted on it out of respect for James. And JK has said that there isn't anything special about Hermione's parents, they are simply dentists and of no importance. If Hermione was James/Lily or Remus/Lily's daughter, wouldn't her "parents" (the Grangers) role then be important? Wouldn't she drag them in for clue purposes? And she's even said before she thought about giving Hermione a younger sister but never wrote her in and if Hermione was to be set up as Harry's sister, then clearly she wouldn't want to be handing her extra siblings, would she? I dunno, just a few random thoughts. If you can put me back on the path of this theory, then I more than welcome it. I would love for it to be true, I really would, but I'm just not completely convinced.

I would have to agree with MrsProfSnape that there are just to many loop holes in this theory and I don't really think they are siblilings. If they were brother and sister wouldn't the Dursleys know about it especially with Hermonie being older? Also, we know that wormtail would tell LV about a sister if it were true because we all know that he can't keep a secret. I think that Harry and Hermonie are just very close best friends and that that brother/sister love for one another and because of that I can see why people would love for this theory to be true.

What a great theory! So much information backing it up too! I actually believe that Hermionie could vary well be Harry's sister. I mean she is a year older than him.

she was born on septmber 19. so she just barely missed that date for being aloud into hogwarts. While Harry got in just short of a couple of months. soooo it makes perfect sense to me that theyre siblings.

It is quite conceivable (excuse the pun!) that Lily could be Hermione's and Harry's mum. But, let's do the math... Hermione was born on 19 September 79 and Harry on 31 July 80. Hermione was 6 weeks old when Harry was supposedly conceived. A woman's body needs at least this many weeks to 'heal' from a pregnancy. This is why obstetricians advise no nookie for at least 6 - 8 weeks post partum! So, Lily could have gotten pregnant when Hermione was 6 weeks old and James could be both Harry's and Hermione's father.

Now, if Lily had had an affair and ended up getting pregnant with Hermione, I would have to ask if she was married to James at the time? Where was James when Lily was being an adultress? Does James know about Hermione? James HAD to have known that Lily was pregnant. It's hard to miss in the third trimester! Perhaps, it was a condition of James, that Lily give Hermione away before he would marry Lily. Maybe, Lily was already pregnant with Harry and she felt she had no choice but to give Hermione away. So, now we have to ask who is Hermione's dad? If I believed in the Sibling Theory, which I don't, I would think that either Lupin or Sirius was Hermione's father. I have read some good posts where many believe that Lupin is the dad.

It could be that someone other than Lily is Hermione's mother. This means that James was cheating on Lily. I wonder if James and Lily were married at the time? Or, was it one last fling of James' before he settled down? I would wonder if Lily ever found out about Hermione? And, who would be the floozy that committed the adultry with James?

We can see all of the very confusing and convoluted scenarios in trying to decide whether or not Harry and Hermione are siblings! It enough to give us all severe headaches! Pass the Extra Strength Tylenol, please.

Personally, I say that they aren't siblings. It could all be a red herring. But I don't think JKR would even consider the Sibling Theory. As I usually say, JKR has way too many loose ends to tie up in that final book. Why would she want to tackle another issue? Another controversy? If she were to do so, the book would be thicker than the bible!

This is my first venture into the discussions pages, so please bear with me, if I'm a little long winded.

I have been reading the sibling theory on and off now for a couple of weeks and whilst I haven't read every reply, I think I have the general idea.

I do not believe that Harry and Hermione are brother and sister and here are my reasons why-

We all must remember that the Harry Potter series are essentially childrens books. Concepts of affairs and illigetimate children are more for adult books. Whilst children and adults enjoy these books, JK wrote for children in mind and we should inflict adult moral standards on to them.

I do believe that Hermione does have an exceptional knowledge of Harry, Hogwarts and all things magical. But I think that this has do with intervension by Dumbledore. How would Hermione get all this information within 6 weeks of being accepted into Hogwarts?

I hope that this all makes sense.

I have read this theory on other sites and actually really like the theory. I would love to see Harry and Hermione be related. Another poster made a reference to the Fidelius Charm being used and I think that if this a true it is a possibility. If this is the case then who is the Secret Keeper.

I have a real problem with the fact that the Fidelius Charm is over looked so much when it comes to theorising. It is played a major part in this series and if it was used one more time to keep Hermione's true relationship to Harry I would be pleased. It is a really important piece of magic.

I have posted a theory on this site on how I think that the Charm could be performed and after reading this thread I think I might add to how it could be applied to this particular theory.

If you would like to read my theory on the Fidelius Charm please see here

noo way..most of the "proofs" were just taken out of context..and they're nothin' but the guessin'..and why would Hermione be just "lily's big secret?" if she is Harry's sister,she's also James' big secret,right?and how could she all these years kept it secret from Harry?I'm sure that,if DD had knew that,he would told him the true..he's simply not the person who can look you in the eyes and lie..Hermione,McGonnagal,Snape an' the rest could not be so good actors..And what about Sirius?why didn't he pay more attention to Hermione?after all,as you said,he is her godfather too..and Lupin,also..and what would happen if Harry had fallen inlove with her?and..Harry is,he has to be,The Chosen one,not Hermione..I mean,the book is called Harry Potter,not Hermione..otherwise,DD wouldn't tell Harry everything he knows about horcruxes..he wouldn't tell him about the prophecy..he wouldn't try to teach him everything he tought that is important for Harry to know..

oh, wow. I just do not know what to say.

Stunned.

I cannot believe I did not realize..it was all righ under my nose this whole time! Whew!!

Great job to the creator of the theory!! I think it should be revealed in Book 7!! And Hermione, such a great secret-keeper, has been trying to sayit all along!


_daviD

wow....wow....im speechless...that makes so much sense and it fits with almost everything.....I really liked the toad theory...Wow... the only thing is, is that Jk Said " Hermione has no brothers or sisters."

I totally agree with the theory and also in HBP When harry says to Mrs Weasly he is not going out with hermione she is relived as though she doesnt want Brother and Sister to go out together. And thats maybe why she sent a small egg at easter ..???? she was disgsted that hermione went out with her brother....its just a guess but i think it has a good point..also when Mr slughorn says to harry is this ure muggle born friend the best one in your year?? Hermione is so happy he said that and is really thankful however Ron says he would have said it to she just smiles a little and turns away..????

I've been following (and occasionally contributing to) this discussion on the CoS forum.

Let me state at the outset that I am not in the slightest way convinced by this theory for many reasons. I won't go into them now as I am currently preparing a detailed breakdown of what I perceive to be the flaws in this theory (and I think I've found a few).

However, I will point out the main objection to this theory that I can find:

On three occasions, in the books, it is stated as a fact that the Dursleys are harry's only living relatives. In an interview, JK Rowling stated that Hermione has no brothers or sisters.

Anything else, really, is meaningless when compared to these statements which state, without ambiguity (despite what Merlin tries to say) that Harry and Hermione are not related.

lots of people have said that Hermionie could be Harry's half sister. Lily and Snape/ Lily and Lupin, but why does it have to be Lily at all. If it was Lily then her friends would have known she was having a baby because it doesn't just happen she would get a bump that can't usually be hidden, BUT if it was James and someone else then Hrmionie could be Harry's half sister because in real life its not always clear who the farther is so that would work no?

The main thing that you have to bear in mind is that, in an interview on August 15, 2004, JKR was asked

I agree with you that JK statement means that she is an only child, period. Making her related to Harry would be too complicated and unquestionable lame. Harry is an only child, Hermione is an only child, non-related friends who will both marry into the Weasley family (hopefully). if they were related, the interest in teh WEasley family would bring bro and sis with bro and sis (i did state this in that new theory about snape and petunia). SO I must disagree with this theory completely.

I dont think Harry and Hermione could be brother and sister. That would be totally copying Star Wars with Luke and Leia! What if then Voldemort turned out to be Harry's real father!

I did actually set out a full and detailed listing of all my reasons for rejecting then Sibling Theory. Unfortunately, my PC recently got severely attacked by Spyware and I had to do a complete system dump and restore. Like an idiot, I had not backed it up to disc. So, from the best of my memory, here are my main objections:

Jo Rowling has said that Hermione does not have a brother or sister.

You can twist and turn her following words in this respective interview as much as you want but, here, she has made a definite statement. When you take this statement along with the comment she made about disposing of Harry's entire family, save the Dursleys, and the number of times it is stated within the text of the books that the Dursleys are Harry's only remaining family, I really do not see how any other interpretation can be reached. None of these statements can be treated as ambiguous in any way. Furthermore, the statements in the book, which are not always from Harry's point of view, are not qualified in any way but are stated simply and directly.

Hermione not being Muggleborn

For me, one of the main driving points that underwrites the entire cycle of books is the whole issue of blood purity. Right from the start, it is made clear that those who subscribe to the 'pure-blood' philosophies are downright evil (Voldemort, the Malfoys, the Blacks), actively malicious (Umbridge) or pompous and bumbling (Fudge). By contrast, those who have rejected the pure-blood philosophies are portrayed in a positive light.

Right from the start, much is made of Hermione being Muggleborn and outstripping most of the other students in her year in most subjects. Similar comments are also made about Lily, mainly by Slughorn in HBP. However, this is not a case of like mother-like daughter. If Hermione was Lily's daughter, the whole concept is pushed off-balance because Hermione would be a half-blood, not Muggleborn like Lily. True, the half-bloods are villified by the purists but not even remotely to the degree that the Muggle borns are. Therefore, should Hermione turn out to be Lily's daughter and a half-blood, the argument Jo has out forth for blood-purity being groundless will be thrown out of the window. Hermione will be possessed of magical blood through her father who was of pure-blood.

Furthermore, it cause a sever disruption to the balance of the triumvirate. As it stands, the balance is between pure-blood (Ron), half-blood (Harry) and Muggle-born (Hermione). There is a pleasing quality about this, in which the three types of wizard put aside blood differences for the greater good. What makes it even better is that this is done by those involved with no thought about it - they simply become friends irrespective of heritage.

Emotional Impact

Should the Sibling Theory be true, the emotional impact on Harry will be devestating. Not only will it disrupt the balance that exists between the three of them, it will also distract Harry at a time when he will need his wits about him.

Various ideas have been advanced as to why Hermione, whom most seem to consider to have full knowledge about this, has not told Harry. One reason is that she was under an unbreakable vow. The mechanics of this notwithstanding, there is one simple, unalterable fact. Harry, upon discovering that Hermione, one of his two closest friends, is, in reality, is his sister will feel shock, hurt and betrayal and most of this will be directed at Hermione. If it transpires that she knew all along will intensify this tenfold. The fact that Hermione was either ignorant of the truth, or unable to divulge it, will be immaterial. Human nature is such that, when we are hurt, we lash out at the nearest target, the innocence or complicity of that person in causing the hurt is not thought about until later.

Character Assassination

Up to yet we have had Albus Dumbledore, a kindly old man with the wisdom of years on his shoulders and hiding a great power. He has been a guide and a mentor to Harry, caring so much for Harry's happiness and piece of mind that he kept much of the truth from him.

Should, as has been theorised, it transpire that Dumbledore kept the knowledge that Harry had a sister from him, he is no longer this benevolent father figure. In his place, we have a cold and calculating manipulator who obviously cared nothing for the feelings of those involved.

It could be argued that Dumbledore kept the knowledge of a sister from Harry because he knew that the knowledge would cause Harry some distress - knowing that she had been delivered to a loving foster family while he suffered the years with the Dursleys. However, surely it would do more for Harry's happiness if he found that he had a sister at the start- a blood-tie being the thing he wanted most in the world (certainly at the start of Philosopher's Stone, anyway). True, he would be angry and hurt when he found out, but that would soon dissapate in the joy of having some family. If this had happened, Harry would not have the six years of deception to handle on top of everything else.

Similarly, this deception does nothing for the character of Hermione. If the Sibling Theory is true, how can Harry trust Hermione, or the memory of Dumbleodre, again?

The Reason

Why was it done? At no point is there anything in the books that suggest a reason why Hermione, if she was Harry's sister, should be hidden. She was not the one in danger, Harry was. There has been nothing to suggest that Hermione is a threat to Voldemort other than the fact that she is a particulalry talented witch and a staunchly loyal friend of Harry who will help in his trials and tribulations. The concept of a secret sibling seems, to me, to be an uncessary subplot that has been grafted onto the cycle as a whole. It seems to jar and not grow organically out of the rest of the story.

There are other reasons but none as important to the points I have made above, at least to my eyes.

And I have not told you once that this isn't Star Wars but...



This Is Not Star Wars
(sorry, couldn't resist it )

It was a valiant attempt. . .but mostly based on coincidental evidence, and a lot of supposition on author intent. (And this thread was amusing with all the little side-plots involving Snape <shaking head>).

Here's the interview question that Slaine mac Roth eluded to, the Edinburgh Book Festival in 2004:

OK, Slaine mac Roth you've done your homework and convinced me.

I think I toyed with this theory because it fixed a lot of what I didn't like.
It gave Harry someone...family who cares, and could be exposed as so after he needed to stand alone. It explained why Hermione's parents seemingly care so little, allowing an 11 - 17(so far) year old girl be away from home constantly. I don't see it as keeping them in the background when they never see her. It was also a good explanation for why DD trusted Snape so much (for warning them and not telling LV)... I hope the real reason is a good one.

Harry and Hermione?! I don't think so. They couldn't be related because of the prophecy. I don't remember the thing saying "There are two chosen ones" but just one! How could Harry and Hermione be related! Then, J.K. would have to concentrate on Hermione more then she normally does. Also, Hermione and Hary were born only a few months apart. You can't have kids that close in age unless they are twins. I don't think they are siblings.

Lachy

Everybody who protects Harry dies, if you're wonderin' ,"Why hasn't Hermione died yet. She has protected him." she has but, not as much as Lily, James, Sirius, and Dumbledore have.Maybe in the last book Hermione will protect Harry and die
Personally I am for the theory.

Yeah, Hermione's birthday is September 19, 1979 while Harry's
birthday is July 31, 1980 (and Ron's is March 1, 1980-yesterday!). Since school starts in either August or September (depending on what school), Hermione would have just missed the age-limit.

That was a whole lot to read... I've always thought it was quite possible.

YEAH! That's totally obvious. Hermione has James' eyes. This will make the H/Hr shippers feel better even if the relationsip thing doesn't happen. Now maybe there will be a H/Hr brother/sister ship.

This is a very possible theroey. I like the family ship thing. It would be really cool if this ended out to be a major part in book 7.

Sugary hugs and choclate kisses,
MJ

I am totally for them being related! BUT! what if they werent brother and sister? i read somewhere about how it cant be possible that ALL harry's relatives are dead. so what if hermiones a cousin? and to explain her bein muggleborn, related through Lily. I particularly like the idea of Harry being a descendant of Godric Gryffindor, it would sort of explain the natural hatred of slytherin people and LV, and i also wonder if anyone else has noticed that the Potters lived in GODRIC's Hollow, this just HAPPENS to be gryffindors first name.

i also have a theory that maybe Harry does have a twin sister, but she turned out to be a squib? or maybe a twin brother?

i have wondered since i first read the books if Harry and hermione are related in some way, but the only way i could see them being brother and sister is if they were twins, this would explain why no one else knew about it,and maybe Dumbeldore had Hadgrid take Hermione to her new parents on the way to droppin Harry off at the Dursleys, it mentions in the first book that they were flying over Bristol, a secret way to say to Dumbledore that he had finished the job? they could still possibly be brother and sister with their bdays stayin the same, and it would still work out, does it ever say exactly how long Lily and James were in hiding for? they could have had Hermione and had her hidden for her own safety! and were planning to have harry hidden soon but LV found them first!

or an even more far-fetched theory would be that maybe Hermione was raised in secret to be Harry's Protector, a guardian sort of person, to protect the line of Gryffindors or Potter's? it is possible that the Potter's were the last living descendants of the Gryffindor line, i mean, the Riddles were the last of the Slytherin's

well i have plenty more crazy wacky nosense ideas but i dont think they fit in with this

I've read the theory and even if it is an impressive piece of work I can't just make sense of it if it were to true. If I were a good writer, as to the means that I could write long and expressive answers I would and it would probably be in the lines of Louise's reply...

I have always disagreed strongly with this theory. It doesn't seem right.

The canon we do have bounces around. It isn't solid. Hermione's parents are muggles. We can be fairly certain that Hermione Granger and Mr. and Mrs. Granger are in the same family. Why shouldn't we? Why should we believe that Hermione was given to them and harry was given to his aunt and uncle?

In my opinion, it is a theory that is moreso of a fan-fiction that anything else. I am not burning the theory, I love good theories,a dn this one was alright. It made some good points. But I just can't believe it. Too much that doesn't make sense, plus the main question of "Why? I mean, whats the point of it all?"

Wow...this really complicates my opinions. I hadn't even thought of this theory until I read it. Now that I think about it, everything would kind of makes sense if this were true. From all of the evidence presented, this seems like a very possible...er, possibilty! I'm eager to read the 7th book to see if we're on the right track.

this is a good theory but one thing that bothers me is that dumbledore sent harry to live with his ONLY blood relatives if hermione was his sister then why didnt dumbledore send him to live with her??....he knew that harry probably wouldnt have too great of an upbringing because of the sort of people the dursleys are and he cares a lot for harry so why not send him to his "sister" hermione..afterall the blood would run through her veins too if she was lilly's child ??...thats why im not really inclined to believe this theory...but its been well thought out though


peace out
D.Axx

Can anyone please explain to me if HG parents are who we are lead to believe then why does she read so many muggle study books. She should know all about muggles.

I don't know really...she could maybe be James's daugther, but then....how much older is Hermione from Harry?
Because I don't think the Potters would have a baby, hide her somewhere, not tell anyone, and then have another baby in a really short amount of time...

Impressive I support the idea.

Wow! It`s a very nice theory and as many of you said very well written.Well, i don`t know i don`t think altough that hermione and harry are brothers. All the things you said it made me think of how strong is their relashionship like FRIENDS. Very close friends.

Maybe it will be possible... i don`t know... from the seventh book i am expecting almost everything.
Look what you`ve done! You got me all confused and thinking about this theory that i will have to re-read the books being attentive to what you`ve said.

One thing i've learnt from HP is NEVER to rule out a theory or possiblilty until it's proven with canon or from the great JKR herself.

I thought this would be very farfetched, but you actually had a lot of evidence to be true!

I'm not sure if it'll be signifigent, but you never know, do you? I've also noticed hermione's sibbling-like ways towards Harry.

Well this theory blows everything out of the water. It's practically the only theory i've read and consindered!

I want to congradulate everyone who helped put that theory together. You did a great job!

-Moon.

I don't think it's likely that Hermione and Harry are related. I mean, if that is true:

A. Harry recieved an album from Hagrid at the end of his first year. Hermione is older than Harry, so that must mean that all of the Potters' friends must have known about Hermione too. Continuing, that must mean that NO photo had Hermione in it, and also Hagrid would know. I don't find that likely.

B. When McGonagall harangued to Harry and George, the line "I do not care if he insulted every family member you possess" idea doesn't have to apply to Hermione. I personally thought she was talking to George more than Harry. I mean, Malfoy insulted both Harry's mother and George's father on multiple occasions.

C. Because Sirius was Jame's best man, it's obvious he would know about Hermione. Also, Lupin and Wormtail would have known. IF WORMTAIL HAD KNOWN, surely he would have begged her to be gracious about his act. Also, I think Lupin would have said, "You owe Harry and Hermione the truth, Sirius!"

D. I think that Hermione would have told Harry if this theory is true and she knew about it.

That's just what I think; I mean, you have a lot of great arguments, but I don't think it is likely. In response to tomziu, I do think it is really unlikely that McGonagall and Dumbledore had a secret marriage.

That’s what I think, anyway. :-) JK Rowling might have put that in there originally, the entire HJP initial issue, but if she did there is no way she would have taken it out if it was THAT significant.

Hello !

This is my first post on the Veritaserum forum, but I've been involved in this Harry-Hermione Sibling Theory for several years now - since 2002 in fact - on various forums. I've also written an essay, which I am currently updating a bit : I can post it here when it's done...

So, just to revive this thread... What new elements have we had from JKR these last few months, that could help support the Sibling Theory ?
I think the NAQ (Never Asked Questions) on her website is highly interesting :

So, there is a "crucial" answer... it is of crucial importance that James had given Dumbledore his cloak.
Also note that JKR is insisting on one important fact : Dumbledore didn't need the cloak for himself (as he can become invisible without a cloak).

So... it seems Dumbledore needed the cloak for someone else. For whom ? It must have been for someone for whom James was willing to give his precious cloak... Someone who meant a lot for him and/or for Lily. Otherwise, couldn't Dumbledore have borrowed one of Moody's cloaks (we know he has a spare one) ?

I suggest this was for James's and Lily's daughter Hermione... James brought Dumbledore more than just the cloak ! He brought him the little girl under the cloak !

i don't think this theory is very likely. you have presented a lot of evidence but the evidence you gave could be labeled as irrelevant (such as the initials part, me and my friend have the same initials and we aren't related). some of the other evidence that you have given that isn't irrelevant can be strongly argued against. after reading through the original post only a handful of the evidence given convinced me. another weak point of the theory was why doesn't Harry know. you have said that it is becuase Harry's mind is connected to voldemort. now that could work but no one knew about Harry having that connection with Voldemort until book five. so why wouldn't he be told before then.

i'm not saying this theory can't be true, i'm only saying that i don't think it is very likely. and that some of the evidence you gave is mostly reading too much into what characters say and how they act.
