The St. Martin church at St. Martinville, LA is not in Lafayette; but it was the mother church for the Atakapas District. Records for these people will be from the later-created Lafayette church because they lived at Vermilion; and the Lafayette church handled their needs until the church in Abbeville, Vermilion Parish was created.
