Black Sisters

Hi,
I'm writing a fic about Narcissa Black, and it's the summer before her seventh year. I know Bellatrix is the oldest, but I'm not sure if it's Andromeda or Narcissa next. I just want to be accurate, so I need to know if Andromeda would still be at home at this time, or would she habe left Hogwarts/been disowned already?

I found this over in the Filing Cabinet, originally posted by Racing Co:

Bellatrix Black (b. 1951)
Andromeda Black (c. 1953)
Narcissa Black (b. 1955)

Hope the dates help. :)

That really helps, thanks. Knowing this adds a lot to my fic.
Thanks Ari.
