Aubert is the French evolution of the Old German name Adalbert — noble (adal) and bright or famous (beraht). The name was borne by numerous Frankish kings and nobles, and entered France through the Frankish aristocracy that ruled the region from the 5th century onward. Its most famous French bearer is Saint Aubert of Avranches, the 8th-century bishop who, according to tradition, founded the monastery of Mont-Saint-Michel after receiving three visits from the Archangel Michael in dreams.
This connection to Mont-Saint-Michel made Aubert a revered name in Normandy, and the Norman conquest of England in 1066 carried bearers of the name to Britain, where it became Aubert, Albers, or merged into the English Albert. In France, the surname became fixed patronymically — son of Aubert — during the medieval period and is particularly concentrated in Normandy and the northern provinces.
Aubert families appear among the early French settlers of Canada. The Auberts of Québec are documented in the Drouin genealogical collection from the 1640s onward, and branches spread through the Saint Lawrence valley and into the Acadian settlements of Nova Scotia and New Brunswick.
Saint Aubert of Avranches (died c. 720) — Bishop of Avranches and founder of the abbey of Mont-Saint-Michel. His veneration gave the name its Norman resonance.
Jean-Louis Aubert (born 1956) — French rock musician, lead singer of Téléphone, one of France's most celebrated rock bands.
Aubert families in North America are concentrated in Québec, particularly in the region around Québec City and along the Saint Lawrence. Acadian Auberts appear in Nova Scotia and New Brunswick, and their descendants are found in Louisiana (Cajun communities) following the 1755 deportation.
Normandy parish records are held at the Archives départementales de la Seine-Maritime (Rouen) and the Archives de la Manche (Saint-Lô). For Québec: the Drouin collection and BAnQ. The Société généalogique canadienne-française holds extensive published family histories. Many Aubert lines were documented by 19th-century Québec genealogists and are available in print collections held by the BANQ.
