They

Saint They is a little-⁠known Breton saint, said to have been a disciple of Saint Guénolé. His story, according to the more or less legendary account of Dom Mars, says that he was born in Armorica of illustrious parents who had come from post-⁠Roman Britain, and that he was entrusted to Saint Guénolé for his education.

According to the cartulary of Landévennec, Idunet, They and Ethbin left the monastery of Landévennec and went up the river Aulne: Idunet stopped at Châteaulin, where he founded the priory of Loc-⁠Yonet; They settled farther upriver, at the place of the Vieux-⁠Bourg de Lothey; and Ethbin went farther still and founded Pleyben. They is said to have led a life of severe austerity there, clothed in a simple tunic and a hood, eating brown bread and vegetables, drinking only spring water, and sleeping on bare ground; many disciples came to him, and the hermitage became a monastery.

His veneration spread quickly in Cornouaille, where he was regarded as a healer of rheumatism. The old parish church of the Vieux-⁠Bourg de Lothey is dedicated to him, and the place takes its name from him. There are also chapels of Saint They at Pointe du Van, at Poullan-⁠sur-⁠Mer, at Plouhinec, and a well of his at Saint-⁠Ségal.
