Cadwy
Cado, Cadway, Cato
Son of Geraint, father of Berth, and one of Arthur’s warriors in Welsh legend.
In the Life of St. Carannog, he is Arthur’s contemporary and perhaps his superior, ruling the castle of Dunster. In the Life of St. Winwaloeus he is Caovius, the king of Britons.
He may be identical to both Cador and Cato (Cado), though the latter is possibly a second-generation derivative.
