Prince who became a hermit in Brittany. The local lord, Grallon, gave Gunthiern land on the Isle of Groie, near River Blavet to found a monastery. It survives today as the Benedictine house of Kemperle.
Legend says that insects once threatened to destroy the region’s crops. Count Guerech I of Vannes, France, requested the saint‘s help. Gunthiern blessed some water and had it sprinkled over the fields. The insects fled, and the crops were saved.
