From https://en.wikipedia.org/wiki/Riothamus

The Old Breton name Riatam, which (like Riothamus) is derived from Brittonic *Rigotamos, appears in medieval Breton records (primarily biographies of early Breton saints) as one of the Princes of Domnonée (a coastal region in Brittany which takes its name from Dumnonia in southern Britain). He is identified as a son of Deroch II. For chronological reasons, this Riatam is probably a different individual from Jordanes' Riothamus, who lived earlier.
