Centwine of Wessex Centwine (died after 685) was King of Wessex from c. 676 to 685 or 686, although he was perhaps not the only king of the West Saxons at the time.
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.
