François Lemay and his wife Marie Gaschet lived in Chesnehutte-les-Tuffeaux, Anjou (also then called Chesnehutte-Trèves-Cunault), where they were married in the 1620s (probably in the Romanesque church of Nôtre-Dame, above). Their son Michel Lemay was born there in 1630, and emigrated to Trois-Rivières in 1654; he died at Lotbinière in May 1685. He married Marie Duteau (daughter of Pierre Duteau and Jeanne Perrin) on June 15, 1659; she was twenty, and a Huguenot emigrant from la Rochelle, but must have converted to Catholicism when she married. They had nine children before Marie died in 1675: Michel (1660-1713, a coureur de bois, married Catherine Jobin, our ancestors via their daughter Marie-Catherine Lemay Gauthier); Joseph (1661-1707, married Agnès-Madeleine Gaudry Bourbonnière, sister of our ancestor Marie-Françoise Pilote, 10 children); Marie (1663, married Louis Houde); Ignace (1665-1725, also a coureur de bois, married Anne Girard); Marie-Jeanne (1666, married Étienne DeNevers dit Boisvert, brother of our ancestor Élisabeth-Ursule Gauthier); Charles (1669, married Louise Houde); Jean (1670, married Marie-Hélène Boucher); Pierre (1671, married Anne Germain); and Marie-Madeleine (1672, married Claude Houde). After Marie died, Michel married Michelle Ouinville and had two more children (Marie-Antoinette, 1680 and Louis-François, 1684). After Michel Lemay died in 1685, she married again, to Louis Montenu.

Marie-Madeleine and Claude Houde were the parents of Marie-Angélique Houde Bourgouin, a great-great-grandmother of Louise Boucher Martin.
