François GIROUARD dit La Varanne, born around 1621, a "laboureur." He married around 1647 to Jeanne Aucoin, daughter of Martin Aucoin and Barbe Minguet and sister of Michelle Aucoin (married to Michel Boudrot). On the 1671 census at Port Royal he is 50 years old; in 1686, age 70 years [sic]. He died before the census of 1693. Between about 1648 and 1660, the couple had five children: Jacques (dit Jacob), Marie, Marie-Madeleine, Germain, and Anne (Anne-Charlotte). . He came to Acadia around 1640 with Aulnay de Chainisary aboard the St. Jehan, shown on the La Rochelle Admiralty Records.  NOTE: he is not on the ship list of 1636 posted here Could not find any other ship lists from that era.
According to the 1767 depositions of their descendants, François and Jeanne came to Acadie as husband and wife. 
Around the time of their daughter Marie-Madeleine's birth (1654), Port-Royal was captured by Robert Sedgwick, who led 300 British soldiers and volunteers. Although the commander of Port Royal left for France, most Acadians, including the Girouards remained in Acadia. They were permitted to retain their land and belongings and were guaranteed religious freedom. Dunn describes life in Acadia during the 16 years of nominal British rule:
"During the years of British rule, most of the Port-Royal population moved upriver away from the town. Using the agricultural practices initiated under D'Aulnay, the Acadians dyked and cultivated extensive salt marshes along the river and raised livestock. Through necessity, residents had reached an accommodation with New England traders who had become their sole source for the goods that they could not produce themselves... New England traders exchanged their goods for Acadian produce and furs... There were seventy to eighty families in the Port-Royal area in 1665."
By the time their youngest child Anne was 7 years old (1667), the British had ceded Acadie to France and French settlement resumed.
"Les Girouard en Acadie ont pour ancêtre François, né en France vers 1621, qui arriva ici aux années 1640. François épousa vers 1647 Jeanne Aucoin, de qui il eut cinq enfants, dont Jacques (ou Jacob), né vers 1648."

↑Statistics Canada defines an arpent as 0.845 acres. According to Clark (Clark, Andrew Hill, Acadia: The Geography of Early Nova Scotia to 1760. Madison: University of Wisconsin Press, 1968, p 87): "The arpent was a basic French unit of land measurement, both linear and areal, but its size at the time is uncertain. In length, 200 feet may be a rough equivalent for an arpent in the seventeenth and eighteenth centuries; it was later standardized to 192 feet. An areal arpent may have been something less than an acre (the usual equivalent was .845 acres) although it has been given the equivalent of as much as an acre and a half in some twentieth century definitions."

It may be possible to confirm family relationships with François by comparing test results with other carriers of his Y-chromosome or his mother's mitochondrial DNA.
However, there are no known yDNA or mtDNA test-takers in his direct paternal or maternal line.
It is likely that these autosomal DNA test-takers will share DNA with François:
