R.A.B.
Near the end of Harry Potter and the Half-Blood Prince, Dumbledore and Harry attempt to recover a locket believed to be a Horcrux created by Voldemort. Instead, they find a different locket containing a message signed with the initials R.A.B. Besides Rosalind Antigone Bungs and Rupert "Axebanger" Brookstanton, two names that Hermione finds while searching for people whose initials might fit, Rudolf Brand, a minor character mentioned once in association with Quidditch in Quidditch Through the Ages and Andromeda Tonks née Black, Regulus is the only character who might match these initials. Rowling was asked in an interview whether Regulus was R.A.B., and, whilst neither confirming nor denying the theory, called it "a fine guess".[1]
[edit] Regulus Black's middle name
In August 2005, the Harry Potter Lexicon fan website claimed to have been informed by a "reliable source" that Regulus' middle name was Arcturus. The Lexicon later withdrew the claim without explanation, but the editor that made the original claim stated that he stands behind the information. He posted the following remarks on The Leaky Cauldron, another fan website:
Obviously, Jo is the source of this information. When have you ever known me to post rumours as facts? It's from Jo. That doesn't mean she talked to me directly, of course, but I do know that it came from Jo.
I honestly think that Jo figures she's already told us that it's Regulus. Read the Melissa/Emerson interview. I think she would be surprised that this is even an issue.
I have asked permission to reveal who told me. If they say I can, I'll let you all know. Otherwise, feel free to take this with whatever grain of salt you need to.

the cave was near the orphanage it could R>A>B three kids from there as he did terrorise then down there??????????????????
OK, but the cave needed advanced magic to find it, and to get to the locket. Unless one of the terrorised children became magical it would have been impossible for an ordinary muggle.
But those 3 children or someone with motivation like that would be a good guess. _________________ Education is the passport to the future, for tomorrow belongs to those who prepare for it today.

It would also be impossible for black...he was 16..harrys age... _________________ Peace is a lie. There is only passion.

I really didn't think too much about figuring out who R.A.B was, but that sounds like a high possibility. But, unfortunately, we will probably not find out for a while, if ever.
Well, so far there is no one with the letters R.A.B. Wait, OMG! I saw a leak for the 7th book and there was someone named --- DO NOT READ THIS IF YOU DONT WANT TO KNOW
Spoiler:
Rivilus - Now, we don't know who that is. But, I am sure of it that is R.A.B.
It can't be Burke because his first name is Caracatus...but it could be Borgin, if he drank the potion and died that would explain his absence from his shop _________________ They say home is where the heart is, so your real home's in your chest. --Captain Hammer
If Mundungus sold the locket, it would mean that Regulus hesitated in destroying the locket, and now it might be roaming around. Also it's interesting that Dumbledore didn't notice it was a counterfeit when he pocketed it. Or perhaps he didn't want to trouble Harry with the fact the expedition was pointless.
Three Reasons Why:
1. He was a Death Eater too
2. He is the brother of Sirius
3. Harry know owns Grimmauld Place and we don't know everything that is in that place. I'm just saying that now that he owns the place he can learn more about it. [/code]
