Hi Fleur Ange,I looked this one up for you on PRDH. They are the only two people of this name on there. 20 years is a long time. Good Luck with your search. Couple # 92503 Jean Baptiste ColpronDeath: 1817-03-30 Burial: 1817-04-01 St. Constant, Quebec. Marguerite Haouste Ops Death: 1803-05-08 Burial 1803-05-10 St. Constant, Quebec.Their marriage date was before 1795 place unknown. I don't know if your know where St. Constant is, but it is on the southshore of Montreal between the Mercier bridge and the Champlain bridge, that should make it easier to find on a map.
