Hello Deborah, I found Louise LAUZIERE-PINARD marriage to Pierre DESMARAIS at St.François Du Lac, Yamaska, Quebec on her parents list as Louis LAUZIERE & Marguerite COUTURIER.I still can not find where Louis fits in yet, but he must be the son of Louis PINARD-LAUZIERE married to Madeleine RENOU on 24 Nov 1698 at St.François Du Lac.Although the marriage wasn't found.I found a François-Regis LAUZIERE having children there about the same time, and he was married to a Therese CARTIER and uses his first name Regis, and is the son of Louis PINARD-LAUZIERE & Madeleine RENOU.
In JETTE book it lists a son of Louis PINARD-LAUZIERE * Madeleine RENOU being born as Jean-Baptiste Louis in 1714.But then in TANGUAY books, it lists him marrying a Therese VERRONEAU (unless he remarried Marguerite Anne COUTURIER using his name Louis).I also found a Louis LAUZIERE-PINARD marrying a Anne VERVILLE at St.François Du Lac on 11 Feb 1771, which could've given their children enough time to grow up and be married.If VERVILLE is the DIT name of COUTURIER, this might be them.
I have other children (siblings of Louise's who list their Mother as Anne COUTURIER instead of Marguerite). here they are:
Marguerite LAUZIERE married François LACHAPELLE 13 Nov 1797 St.François Du Lac
Josephte LAUZIERE married 20 July 1795 Jean JOYAL at St.François Du Lac.
I hope this helps.Contact me at firstname.lastname@example.org or email@example.com
