At least a dozen unrelated Thibault families can be found in Québec. Ours originates, like many other ancestors of Marie Eva Jean Martin, in the Île de Ré, specifically the parish of Ste-Catherine de la Flotte (above). They must have known the Migniers, with whom they later intermarried.

Louis Thibault was married there, on October 29, 1643, to Renée Gauthier (not related to our other Gauthier ancestors, who were from Paris). We know of seven children: Marie (1644); the immigrant François-Louis, (baptized at Ste-Catherine on June 18, 1647); Louis (1649); Jacques (1652); Catherine (1655); another Marie (1658); and Jean (1660).

François-Louis Thibault signed an indenture in La Rochelle on March 31, 1665, and was in Beaupré later that summer. He had just turned eighteen, and was working as a farmhand. He married Élisabeth-Agnès Lefebvre on October 14, 1670 (she was a recently-arrived fille du roi). They had twelve children, the first born at Beaupré, the next two in Québec city, and the rest in Cap-St-Ignace. Marie-Élisabeth (1673-1756, married Jacques Bélanger and Martin Rousseau, brother of our ancestor Marguérite Rousseau Morin); Jean-François (1675, married Marie-Anne Guimont, sister of our ancestor Joseph-François Guimont); Jacques (1678-1755, married Marie-Anne Proulx); Marie-Anne (1680-1736, married Jean Dumais); Marie-Geneviève (1682-1726, married Jean-François Bélanger); another Marie-Anne (1684, married Louis Cloutier); Marie-Angélique (see below); Marie-Madeleine (1688, married Charles Gaudreau); Marie-Barbe (1690, married Nicolas Fournier); Joseph (born and died 1692); and Louis (1695-1765, married Cécile Fournier).

Marie-Angélique Thibault was born at Cap St-Ignace on February 15, 1686, and died at La Pocatière on February 8, 1736. She married Michel Mignier dit Lagacé on July 28, 1705 at Cap St-Ignace. See Mignier dit Lagacé for descendants.
