I think that when Moody said "the Bones", he was refiering to Susan's uncle and his wife, we know nothing about the parents of Amelia Bones.
That's just my opinion, please think about it and if you think, I'm right, remove the corresponding pages (if you can).

- To quote from the interview linked in the article (Barnes and Noble & Yahoo! chat with J.K. Rowling, barnesandnoble.com, 20 October, 2000):
- matiaskanfunfa: "There is a girl named Susan Bones who was sorted in the first book and there was a family called the Bones that Voldemort tried to destroy, is this a coincidence or will Harry meet her in future books?"
- J.K. Rowling: "Susan Bones' grandparents were killed by Voldemort!"
