my question is, How come Professor McGonagall couldn't marry Dougal McGregor... he was a muggle yes.. but alot of the students at Hoqwarts have half and half... like Seamus. Snape had half and half... even Voldemorts pops was a muggle. yeah i was just wondering why she couldn't do it but everyone else can. —The preceding unsigned comment was added by 74.132.115.61 (talk • contribs).
