Does anyone know of a Jean-Frederick Duffenias (Dauphine) who was married to Marie Anne Catherine Lejeune. They are my ggg grandparents. They have a son, Jean Duffenias born around 1820 and died in 1904 in Winterhouse, Port au Port Penn. Jean Duffenias was married to Adelaide Gaudet, her parents were Jean Gaudet and Pelagie Cormier. Any info will be greatly appreciated.
