Where the Harrison name comes from

Harrison is a patronymic surname from the north of England, meaning son of Harry. Harry was the everyday Middle English form of the given name Henry, so the name records a father called Henry as much as one called Harry. The surname was first recorded in the 14th century. It was also spelt Harrisson, Harryson and Harrysson, and a form Henrison appears in old records but has since fallen out of use. Early records show some families using Harrison and Harris interchangeably.
