Marriage of Francois Xavier CLERC and Therese ORIEZ 23 April 1818http://www.archives.cg90.fr/?id=viewer&doc=accounts%2Fmn...
Xavier CLER aged 22, born 10th pluviose Year V, son of late Thiebaud CLER and of Catherine BARBARET of this place.
Thereses ORIEL born 22 Feb 1792 daughtere of Vincent ORIEL and of the late Marguerite ?refeneur?? also of Rougegoutte.
