In 1666 the first census was made of New France. The Moral household at that point in time consisted of: "Quentin Moral sieur de Saint-Quentin, 44, habitant ; Marie Marguerie, 40, sa femme; Jeanne, 13 ; Marie, 10 ; Gertrude, 8 ; Marthe, 5 ; Robert Henry, 20, et Nicolas Dupuis, 24, domestiques". Marie's daughters by Jacques Hertel had already married and left the house. Trois-Rivieres and adjacent districts had grown in 20 years from a handful of settlers to a village of 69 families and 455 souls. However the town itself still consisted of only about two dozen households and less than a hundred Europeans.
A year later, the census showed that one servant had left but that otherwise the household was much the same: "Quentin Moral, 49 ; Marie Margris, 40 ; Marie-Jeanne, 14 ; Marie, 12 ; Gertrude, 10 ; Marthe, 6 ; Robert Henry, domestique, 23 ; 6 bestiaux, 64 arpents en valeur. (6 cattle, 64 arpents in value.) "
Quentin also saw that his daughters would marry well and that their husbands were provided with adequate dowries in terms of land and titles. In late 1667 Marie-Jeanne was married to Jacques Maugras at the age of 15. Quentin's sisters families would eventually all move to St-Francois-du-Lac, the settlement founded by Jean Crevier. Crevier was the husband of one of Marie Marguerie's daughters by her first husband, Jacques Hertel.
In 1676, at age 18, Gertrude Moral was married to Jacques Joyelle, a master gunsmith. With the assistance of the legal machinations of his father-in-law, Joyelle would obtain a seigneury, then later move to St-Francois-du-Lac near his brother-in-law Jean Crevier.
Marie Marthe Moral was married in 1682 at the age of 21 to Antoine Dubois, who was in his thirties. Nothing appears to be known of his birthplace or profession. Quentin Moral had already engineered a complex land swap whereby Marthe's brother-in-law, Joyelle, moved to St-Francois-du-Lac, whereby Dubois obtained a property there, despite his evident inability to pay. Marie Marthe's family would join those of her sisters in St-Francois-du-Lac, and spend the balance of their lives there.
