I think I may know who R.A.B is. I think it is Sirius' brother Regulus 
Black. (Order of the Phionex (family tree)) 

It would tie in so well...
# 5 says that Regulus Black became a death eater but something 
happened and Regulus Black tried to leave the bad influence group and 
He Who Must Not Be Named killed him himself.

I think that maybe Regulus didn't like He Who Must Not Be Named's 
horcrux idea so he switched the horcrux and destroyed the real one. 
Then He Who Must Not Be Named found out and killed him.
