French: diminutive of Chauve, a nickname for a bald man, from Old French chauf ‘bald’ (Latin calvus).
FOREBEARS A Chauvin from the Maine region of France is documented in Quebec city in 1647, with the secondary surname Ste. Suzanne. Another Chauvin family, from Anjou, represented by ‘Grand’ Pierre Chauvin, was in Montreal by 1653. Three of his sons were with Jean-Baptise Le Moyne, Sieur de Bienville, in Biloxi in 1700, and a fourth joined them in 1706. They settled in New Orleans, where their descendants achieved great prominence. Some adopted secondary surnames which in due course superseded the Chauvin name, for example (De) Léry, (De) La Frenière, and (De) Beaulieu.
