Legacy; Cassiopeia black

What if regulus never died? What if he had a daughter?

This is who Cassiopeia black is. The daughter of regulus black and Bertha Jorkins. Her mother died giving birth and she is left to be raised by her father. When she turns 11 she gets her letter from Hogwarts. Will she live up to the black name and get placed in Slytherin or follow her uncles path and get placed in Gryffindor? Time will tell.
