The early 5th century Prince Guitol is recorded in
the Lives of Saint Winnoc and of Saint Judicael as the son of "Urbieni
filii Catoui filii Gerentonis". Thus the rulers of the Continental
Domnonée are shown to originate from the British Dumnonia. Unfortunately,
however, it is chronologically impossible for Guitol to have been the grandson
of King Cado
of Dumnonia. It seems probable that Catoui is, in fact, a transcriptual
error for Cononi. Conan
Meriadoc was the son of Gereint
ap Einudd, and his son was, of course, the great Breton King, Gradlon
Mawr alias Urban.
Upon Gradlon's death around AD 421, his kingdom, therefore,
appears to have been divided amongst his sons in the usual Celtic manner.
Saloman, as the eldest son, took the Breton heartland of Cornouaille and the
over-kingship, while Guitol became the first Prince of Domnonée.
