Le Borgne inherited his rights in Acadia from his father, who, in turn, claimed the governorship and seigneurial rights in Acadia on the death of d'Aulnay in 1650, due to large debts owed. Although the governorship passed to Hector d'Andigné de Grandfontaine in 1670, Le Borgne exercised seigneurial rights over Port Royal until his death.[2]
The seigneurial rights asserted by the Le Borgne father and son since 1650 were always disputed by the heirs of d'Aulnay, and would be settled by an edict from the French Royal Council in 1703.[2]
