Ever wonder how J.K. Rowling came up with the names for the Death Eaters?

Here's part of her terrific commencement speech at Harvard:
“The friends with whom I sat on graduation day have been my friends for life. They are my children’s godparents, the people to whom I’ve been able to turn in times of trouble, friends who have been kind enough not to sue me when I’ve used their names for Death Eaters.”

Via.
