My friend had this question. I swear I read something about this here, 
but I forget, so I'm posthing this :)

-----------------------------------------

I suddenly thought about this. How did Sirius really get his parent's 
house?

Yes, it goes to the last living Black, who was him, but he was 
disowned. Wiped from the Black family tree. Not to be given a cent of 
their money. Normally, if one is dead and the other disowned (meaning 
he wasn't alive in the first place, in their minds), then shouldn't the 
inheritance go to Narcissa or Andromeda? And if it can be handed only 
to males, shouldn't it all go straight to Draco, the only male left 
with Black blood?

I found this puzzling, at any rate.
