Marguerite Fontaine was born about 1697 in Canada, Nouvelle-France. Her parents were Pierre Fontaine and Marguerite Anthiaume. (DOB estimated, no baptism found for her, and her funeral gives no age; her parents moved locations between 1693 and 1699, so place of birth is uncertain.).
Marguerite Fontaine, daughter of Pierre Fontaine and of Marguerite Anthiaume, married Paul Desmarais, son of Paul Desmarais and Marie Tetreau, on 23 April 1715 in Contrecœur. 
13 known children from this marriage, 6 known to die young and 6 to marry.
Paul Démarêts, from Verchêres, died on 11 December 1739 and was buried on the 12th in Sainte-Anne-de-la-Pérade, having died of hydropisie in the house of Yves Phlem, surgeon.
Marguerite Fonteine, widow of Paul Marais, remarried with Joseph Leduc, son of Charles Leduc and of Angélique Chevalier, on 9 January 1745 in Verchères. No issue from this marriage.
Marguerite Fontaine dite Bienvenu, wife of Joseph Leduc, passed away on 5 May 1766. Her burial was two days later in Verchères.
