Frithuwold of Chertsey

Frithuwald was a seventh-century Anglo-Saxon ruler in Surrey, and perhaps also in modern Berkshire and Buckinghamshire, who is known from two surviving charters. He was a sub-king ruling under King Wulfhere of Mercia. According to late hagiographical materials, he was a brother-in-law of Wulfhere. The monks of Saint Peter's Minster, Chertsey, revered Frithuwald, whom they considered the founder of their monastery, as a saint.
