Correct me if I am wrong, but I was under the impression that Lily and 
Petunia's parents were both Muggles.  If so, how could there be any 
relation to the Blacks, who are generally all pureblood wizards?  
Also, wouldn't Sirius have already known if he was in any way related 
to Harry?  Wouldn't he have been eager to tell Harry?
