And, if I go with the fact that Dorea (?) and Charlus Potter were indeed the Potters, (she died in 1977, which, if I use the most commonly accepted fanon timeline, means she died in James' final year at Hogwarts) but she was supposed to have lived a long wizarding life. Surely, 57 is not a long wizarding life. Also, why wouldn't Harry have noticed the surname Potter on the tapestry, and why wouldn't Sirius have pointed it out?
Oh Jo, you are kerazy. Plus, I really like the fact that there are two other Siriuses (I really have to quell the urge to type Sirii) in the family line. This is so exciting. The Flints, Crabbes, Longbottoms, and Crouches are all related to the Blacks. If I allow for some vowel gradation over the years in surnames, then the MacMillans (McMillan) and the Prewetts (Prewitt) are also on the tapestry. We knew the Prewetts were purebloods, but the MacMillans are so much fun. Hufflepuff purebloods? WILD!
I am so excited about this. I could go on and on.
