Saint Ténénan (or Saint Thénénan) is one of the mythical Breton saints of Armorica. He is known as Tudogilus (or Saint Tudon or Saint Thudon or Saint Tugdon), as the father of Saint Gouesnou, Saint Majan and a girl named Tudona. Records suggest Saint Ténénan and Saint Tudon immigrated to Brittany at the same time, frequented the same places and therefore may be one individual.
