Charles Le Moyne  received the title of  Baron de Longueuil in 1657, but his son inherited that title when he died in 1729.
Charles (II) le Moyne de Longueuil, Baron de Longueuil (December 10, 1656  June 7, 1729) was the first native-born Canadian to be made Baron in New France. The title Baron de Longueuil was granted originally by King Louis XIV of France to a Norman military officer, Charles le Moyne de Longueuil, and its continuing recognition since the cession of Canada to Britain is based on the Treaty of Paris (1763), which reserved to those of French descent all rights which they had enjoyed before the cession. The title descends to the heirs general of the first grantee, and as such survives today in the person of Michael Grant, the 12th Baron de Longueuil, a cognatic descendant of Charles le Moyne de Longueuil, the 1st Baron. The Seigniory of Longueuil was first granted in 1657 to Charles Le Moyne de Longueuil et de Chateauguay, Sieur de Longueuil, and was raised to the label of Barony of Longueuil in 1700 by Louis XIV in recognition of Le Moyne's services. Charles Le Moyne died in Montreal in 1729, and the barony passed to his son, also named Charles Le Moyne (16871755), the second baron.
