The surname Boisvert was first found in Normandy (French: Normandie), the former Duchy of Normandy, where they held a family seat in the seigneurie of Bacqueville and were members of the aristocracy of that region.
The earliest of the name on record was Jean Boivan Champeaux, a senator of Normandy living in the 11th century about 1070. Of this main stem of the family Louis Boivin joined William Duke of Normandy in his invasion of England in 1066 and became Chancellor of England and Bishop of Ely. The main stem branched to Bonnetot in Normandy and to Martinière. This latter branch survived the revolution and became Barons of the Empire in 1810. They also branched to Brittany. Meanwhile, an important branch moved to the Franche-Comté. Most other branches lost their estates during the revolution of 1789. The family received letters confirming their nobility in 1826.
