My father and mother would have used these titles if it weren’t for Voldemort, you know. So would have the other prominent Pureblood families. He didn’t care to be a king, but he cared enough to put Lord in his name although it didn’t belong to him. And because he was a Lord, nobody else could be. He forced everyone to stop using their titles so he would be above them all, and he got what he wanted. I wasn’t sorry to see him perish.
