Abraham Duga's burial record in 1720 gives neither his age nor martial status. Without other proof , it is impossible to tell whether this was Marie Madeleine Landry's husband, Jeanne Guilbeau's. At the time of Joseph Dugas's marriage (Rg PR7 Jan 1728) the groom's father was already dead. It was thus Marie Madeleines Landry's husband wh died in 1720 after a long illness. The other Abraham Dugas appears in the censuses at Port Toulouse until 1734.
A map of 1707 mentions Abraham Grivois. This was clearly Abraham Dugas, who was also known by his step-father Claude Guedry's nickname.
