The Harry Potter Muggle, according to Ancestry.com, is related to a 16th century...witch?
Researchers have found records that indicate one of Watson's distant relatives was Joan Playle, an unmarried woman from Essex County, England, who was convicted of witchcraft way back in 1592.
Ms. Playle wasn't executed for her alleged crimes, but she was excommunicated from the Church of England.
Guess all that big-screen hocus-pocus isn't a stretch for Hermione's alter ego!
