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.
The princeps Frithuric who was active in Mercia in the reign of Wulfhere's brother and successor Æthelred is presumed to be a kinsman of Frithuwald, perhaps his son.
[4] The possible Frith family may also have included the eighth-century figures Saint Frithuswith, and Frithugyth, wife of King Æthelheard of Wessex.
[5] Two charters issued by Frithuwald to Eorcenwald, Abbot of Saint Peter's Minster, Chertsey, and later Bishop of London, survive.
The core of these lay in the lands of the Woccingas, around modern Woking, probably bounded by the Fullingadic, perhaps an earthwork although it has been suggested that it could instead have been a Roman road, to the east.
