Jean Dugas was born on March 28, 1764 in Boulogne Sur Mer, Picardie, France, while his Acadian parents Claude Dugas and Marguerite Cyr, were in exile.
He married Jeanne Cabon, daughter of Jean Cabon and Françoise Danion, on 3 August 1784, in Chantenay, Bretagne, France. 
In September 1784 in Nantes, France, they appeared on a list of Acadians
wishing to "go to Louisiana to establish themselves at the expense of His [Spanish] Catholic Majesty." Also on that list was Jean-Pierre’s sister Marguerite. 
They emigrated to Louisiana aboard Le Beaumont, arriving in New Orleans on 19 August 1785. 
He died before 10 July 1786 since Jeanne remarried on that day.
