This is great, but some of it is actually incorrect! Quite a few of the names JK Rowling used for characters were actually pulled from a cemetery in Edinburgh, Scotland near the cafe where she wrote the first book (it’s called the Elephant cafe). Many of the names, including Tom Riddle and McGonagall (as well as Moody) were pulled from gravestones. I’ve visited the cemetery myself and it’s very cool to see!

Another fun fact: the cemetery as well as a primary school are visible from the cafe’s windows. The primary school has four towers, which was part of the inspiration for the four houses :)

This is a great guide otherwise, thanks for sharing!
