Yaxley family

Yaxley is the surname of a pure-blood wizarding family, and one of the Sacred Twenty-Eight. They are related to the Black family, and more distantly to the Crouch, Weasley, and Longbottom families. It is likely that the Yaxley family originated in Scotland as Yaxley speaks with a strong Scottish accent.
