François Morneau was born about 1624 in the parish of Notre-Dame-du-Bon-Port, in the small town of Les Sables-D'Olonne, diocese of Lucon, Poitou. This today a resort town (pictured above), on the Atlantic coast about halfway between Nantes and La Rochelle, and only a few miles north of the Île de Ré, where so many of our ancestors originated.

Evidently François Morneau married Marie Mornet in or before 1646, when he travelled to Québec without her; their only child Jean was born in 1646 or 1647 in Les Sables-D'Olonne. He was a soldier, an "arquebusier," and perhaps decided to stay in Canada because Marie died; there is no record of her having crossed the Atlantic, and he acquired land in Batiscan. Jean Morneau was in Batiscan by 1674, and in February 1675 he married Geneviève Tru, daughter of Mathurin Tru (or Trud, or Trut) and Marguerite Gareman, at Sillery. He was dead by 1673, because in that year she remarried. They had at least four children: Jean-Baptiste (1679), François (1682), Pierre (1685, married Marie Bibeau), and Marie-Louise (1690, married Jean Ricard).

The second François Morneau married Angélique Bernier (daughter of Pierre & Françoise Boulay or Boulet) at Cap St-Ignace in October 1713. They had fourteen children, all born at either Cap St-Ignace or L'Islet: Marie-Angélique (1714), Jean-François (1716), Pierre (1717), Basile (1719), Marie-Claire (1720), Alexis (1722), Geneviève (1723-1724), Louis-François (1725-1728), Félicité (1727), Salomé (1729), Marie-Françoise (1731), Marie-Josèphe (1735-1742), and Marie-Madeleine (1737-1738).

Marie-Angélique Morneau married Noël-Marie Dupont (son of Guillaume & Anne Trottain) at L'Islet in February 1737. For their nine children see Dupont. Their daughter Claire (born 1746) was a great-great-grandmother of Marie Eva Jean Martin.
