In his princely years before the death of his father Cuthwine had at least three sons; Cynebald, born 585; Cedda, born 590, and Cuthwulf, born 592. The name of their mother is not recorded, but it is possible that she died in the tumult surrounding Cuthwine's flight into exile given that Cuthwine had no more children after that time. Cedda became the father of Coenberht, in turn the Caedwalla of Wessex and his brother Mul of Kent, both kings in later years. Through Cutha Cathwulf, Cuthwine's youngest son, were ultimately descended the Kings of Wessex after the line of Ceol became extinct in 685.
