Biography
Pergat was born into a noble and wealthy family around 548. He was a student of the Breton monk Tugdual who established a hermitage on an island off the coast of North Wales. Pergat accompanied Tugdual when the latter returned to Brittany, probably settling at Yaudet near Lannion.Le Grand, Albert. Vie des saints de la Bretagne Armorique, 1636, réédition 1901, Quimper
A good speaker, Pergat became Canon and Archdeacon of Tréguier. On the death of Tugdual, he contested the election of bishop Ruelin and, supported by a part of the people and clergy, was also elected. To settle this schism, a synod was summoned to Lexobia, marked by an apparition of Tugdual, who threatened Pergat with a terrible and rapid punishment if he did not withdraw. Pergat knelt down, begged pardon, and retired to Pouldouran, of which he is still the patron saint and where a fountain bearing his name exists. He ended his days by doing penitence as a hermit at Ty-Bergat. He died around 620. M. de Garaby. Vies des bienheureux et des saints de Bretagne (1839) - Saint-Brieuc
