François Gautrot or Gautreau was born in the Touraine, but the exact place and his parents' names are unknown. Census data suggest he was born in 1613. He was in Port Royal (above), Acadia by 1636, evidently with his first wife Marie (last name unknown). They had two children: Marie (c1636, married ? Potet and then Michel Dupuis); and Charles (c1639-1714, married Françoise Cousin, 6 children). About 1644, François married Edmée (sometimes Aimée) Lejeune (see below). They had eight children: Marie (c1645, married Claude Terriot); Jean (1648); Renée (c1652, married Jean Labat); Marie-Marguérite (c 1654-1727, married Jacques Girouard, 14 children); François (c1657, married Marie-Sébastienne Brun, 8 children); Claude (c1659, married Marie Terriot, 13 children); Charles (1661, married Françoise Rimbault, 11 children); Jeanne (c1665, married Pierre Lanoue); and Germain (c1668; became a coureur de bois and disappears from the censuses).

Edmée Lejeune is a mystery. We know nothing about her background, only that she had a sister Catherine (born about 1633) who married François Savoie. There was only one Lejeune in Port-Royal in the 1620s, when the older sister was born - Pierre, and he was unmarried. Pierre Lejeune was in Acadia as early as 1611, with the very first settlers; they were all male, and several married Micmac women. The assumption is that Pierre did the same. This is quite possible, but not documented in any way. Micmac women who married French settlers usually converted to Catholicism and received Christian names, which are often recorded. On the other hand, Pierre could have had a French wife who left no record, and Edmée could even have been born in France. But the fact that so many Gautrot children were born and recorded, and then disappeared from later records, suggests that they lived with their Indian relatives.
