BTW, something else which just occurred to me-- I wonder if this legend about Cunmar the Accursed and St. Triphine (with the werewolf curse) is heard of anywhere outside of France, if it spread beyond France/Brittany to French-influenced areas of the Americas? French settlers in the Americas came from all over France, including Brittany, so it's plausible that Breton colonists may have brought the story where they settled.
