^mbkomer might not know that JK Rowling revealed Andromeda's house, which would make it an opinion question.

I've read that it's been confirmed that she was in Slytherin (that Sirius was the first and only Black to be Sorted outside that House). But I'd have thought she'd be in another House otherwise.
