William Alderton

William Olderton was the father of Olderton, a wizard who was tried for allegedly being a Muggle-born by the Muggle-Born Regstration Commission. Because the commission found Olderton guilty of this, it is likely that he was a Muggle. Despite this, his son claimed on leaving his trial that his father was a half-blood, for which William Olderton must have been a Pure-blood wizard. He also claimed that he once worked for the British Ministry of Magic. This is probably untrue, however.
