J .K. Rowling is once again shaking up the entire "Harry Potter" universe.
In her latest Pottermore post, the author revealed that the Harry we all know had a great grandfather called Henry Potter – but he was known as Harry to friends. The character of Henry Potter "served on the Wizengamot from 1913 - 1921." “Henry caused a minor stir when he publicly condemned then Minister for Magic, Archer Evermonde, who had forbidden the magical community to help Muggles waging the First World War."
