Career
Participant of the Ancien Régime, the Gaultier family of aristocrats came from the Anjou area of France. René married the daughter of Pierre Boucher, the governor of Trois-Rivières in 1667 and part of the marriage contract contained a request to the governor of New France, Daniel de Rémy de Courcelle, that he should retain the office and the privileges of his father-in-law when Boucher retired. Boucher did retire in 1667 and René became governor.
