Yorkshire is a county in northern England. In Yorkshire is the small village of Upper Flagley. Upper Flagley is one of the places in Great Britain where a number of magic families came to settle among Muggle neighbours. In the early 15th century, Beedle the Bard was born in Yorkshire. Two wizards seen in the Hog's Head in 1995 likely came from Yorkshire, as they were talking with Yorkshire accents.
