Jean Dubé and his wife Renée Suzanne lived in the small village of Chapelle Thémer near Fontenay-le-Comte in Poitou in the early seventeenth century. Sometimes his wife is cited as Suzanne Renée. Both of these are very dubious as surnames; probably when their son got married in Québec and had to give his parents' names, he did not know his mother's maiden name. We know of four children, baptized in the church at Chapelle Thémer (above), though the actual records are lost: Philippe in about 1630, Mathurin-Jacques about 1631, Simon about 1634, and René about 1637.

The second son, the immigrant Mathurin Dubé, came to Nouvelle-France in 1659 or 1660 (probably 1659, with François de Montmorency-Laval, his future landlord). There he married a "fille du roi," Marie Campion, on September 3, 1670 at Ste-Famille on the Île d'Orléans. The 1666 census records him as a "laborer." He owned a small farm at the parish of St-Jean in the Île d'Orléans, but sold this in 1684 to move to a larger one across the river at La Pocatière. He died there in 1695, and his wife in 1703.

Children: Mathurin (baptized January 27, 1672, Ste-Famille, died after 1725 and before 1728 at Rivière-Ouelle); Marie-Madeleine (baptized September 17, 1673, Ste-Famille, died June 14, 1749, Rivière-Ouelle); Louis (baptized. May 19, 1676, Ste-Famille, died February 28, 1747, Rivière-Ouelle, married (1) Angélique Boucher, daughter of Pierre Boucher and Marie-Anne St-Denis, on January 28, 1697, Rivière-Ouelle, and (2) Marguérite Lebel, January 9, 1719, Rivière-Ouelle); Pierre (baptized December 8, 1678, Ste-Famille, married Marie-Thérèse Boucher, Angélique's sister, on January 7, 1704, Rivière-Ouelle); Charles (baptized October 27, 1680, St-Jean, Ile d'Orléans, died in or soon after 1681); Laurent (baptized April 18, 1683, St-Jean, died April 8, 1768, LaPocatière, m. Geneviève Boucher, another sister of Angélique, on January 7, 1706, Rivière-Ouelle), and Jean-Bernard, baptized January 5, 1694, Rivière-Ouelle).

Laurent and Geneviève Dubé had ten children: Marie-Angélique (1706); Joseph (1708, married Marguérite-Barbe Cloutier, 7 children); Marie-Madeleine (1710-1759, married Jean-Baptiste Pelletier, 14 children); Laurent (born and died 1713); Marie-Josèphe (1714, married Ignace Lebel, 11 children); Simon (1717, see below); Geneviève (1719-1738, married Augustin Lebel, one daughter); Jean-François (1721, married Marie-Charlotte Saint-Pierre, 8 children, and Marie-Catherine Lebel, 6 children); Pierre-Jacques (1724, married Marie-Anne Pelletier, 7 children); and Marie-Françoise (1730, married Charles-François Gauvin, 6 children). The older children were born in Rivière-Ouelle, but the younger ones in St-Roch-des-Aulnaies, where they family had moved about 1716.

Simon Dubé was born in St-Roch-des-Aulnaies and baptized on April 11, 1717. He married Marguérite Gaudin or Godin on January 11, 1738 at St-Roch-des-Aulnaies. She was a daughter of Pierre Gaudin and Catherine Pellerin. Their children: Jean-Marie (1738); Marie-Josèphe (1740, married Pierre Jean on May 14, 1764 at St-Roch-des-Aulnaies); Joseph (1743); Marguérite (1744-1745); Jean (1746); Marie-Rose (1748); Jean-Baptiste (1750); Pierre-Noël (1752); Simon (1754); Marie-Thérèse (1756-1757); Jean-Bernard (1757); Jean-Roch (1760); Pierre-Roch (1761); and Marie-Ange (born and died 1762).

Pierre Jean and Marie-Josèphe Dubé were great-great-grandparents of Marie Eva Jean Martin.
