Guenin of Vannes

Saint Guenin of Vannes (also called Gwennin) was the tenth bishop of Vannes, in the 7th century according to the French source, though our record places him in the 6th. He is venerated in the Western Church and remembered on 19 August according to the calendar of the Breton saints.

The commune of Guénin in Morbihan took its name from him. At Brech there is a chapel of Saint-⁠Guénin, also called Saint-⁠Quirin; it is not certain to whom it is dedicated: to Guenin, to Quirin, to a Breton saint called Quiry, or even to the Roman god Quirinus. No other information about his life survives.
