Can anyone tell me if there's a definite reference to Parvarti Patil surviving the Battle of Hogwarts? I'm forming a story which basically requires her to have been killed in the battle. I know she was at Hogwarts at the time of the battle, and that her best friend was injured (presumably badly, from "feebly stirred"). I also know that there's nothing stating she was killed, but that doesn't mean she survived.

I just want to make sure that I can make that assumption before writing my story.

Many thanks
