Kathy W:
I think the most likely explanation is that JKR made a comment or 
plot change at some point that contradicted something else and set us 
up for all this math. Try as I might, I can't leave it at that.

It's very likely she intended the 3 Black sisters to include one who 
was disowned and was the mother of a auror who befriends Harry. And 
she intended the other two sisters and their cohorts to be involved 
with the boy who would become Postions Master. Unfortuneately, she 
gave an age or date for a character in an interview and it all fell 
apart. How important is age to her, if she OKed Rickman for Snape? 
(I'm glad she did, mind you.)

In case we've created our own red herrings, is there a chance that 
young Snape was connected with either Rosier or Avery prior to coming 
to Hogwarts and Sirius's comment reflects that Snape came to school 
knowing more hexes...and came to school already a part of a gang of 
Slytherins that included....

Sirius's wording is very strange in that section from the get-go.

It looks very likely that Rosier was cousin to the two sets of Black 
siblings. Could he also have had a connection with the Prince family? 
Severus didn't learn Dark Magic from his Snape cousins. Although he 
may have learned other unsavory lessons from them.
