I'm going off Maggie Smith's birthday, that's the actress for Minerva McGonagall.If you don't know who the professors were before Minerva was in the original books, I'll give a list.

This is strictly to give a better idea to you guys, and partially to me. It helps to know who some of the characters are! And yes, I did put people's parents in here because I was running out of characters. I did sas much research as I could but Google doesn't have everything I needed for this. Oh well. Have fun!
