I have a bit of info for you from Rene Jette's "Dictionnaire Genealogique des Familles du Quebec, des origines a 1730".
Gabriel's last name is given as Millot (also seen as Milhault). He and his wife, Julienne Philippot, lived in Crouzille, Laval, Le Mans, Maine, France. Son Jacques (b. about 1632 & died in the hospital in Montreal on Aug. 15, 1699) arrived in Montreal, Quebec on Nov. 16, 1653. He married Jeanne Hebert March 7, 1660 (Montreal). They had 11 children but only one son survived. I have no record of the one son ever marrying as he headed west in April, 1688.
