A lot of beloved characters were killed off in Deathly Hallows; there were literally corpses lined up in the Great Hall. However, there are a lot more characters in the Harry Potter world whose ultimate fate was not explored, at least not in the books or movies.
What I'm asking, then, is if JK Rowling ever retroactively killed off any more characters after publishing Deathly Hallows. For instance, in interviews or on Pottermore.
- If they died in the movies but not the books, they don't count (so not Lavender).
- If they were not seen alive (and not in flashbacks/magic mirrors) in the books or movies, they don't count (so not, for instance, Harry's grandparents).
- Time of death should be between Harry's birth and the epilogue of Deathly Hallows (so not 'everyone dies eventually').
- Works by other writers (Cursed Child, etc.) do not count.
