Family name origins & meanings
- French : habitational name from any of the extremely numerous places in France named with Old French beu, bel ‘fair’, ‘lovely’ + lieu ‘place’, ‘location’. The name is occasionally also found in England; it is then either a Norman name from one of the French places just mentioned or derives from an English place name of the same origin, Beaulieu (pronounced byoo-lee) in Hampshire, seat of the Montagu family.
- In Canada Beaulieu has been used as a secondary name to Diers, Dufresne, Hudon, Lebel, Martin, Montpelier, Palmier, Philippe, and Thomas. It is documented independently in Montreal in 1726 as the name of an immigrant from Gascony, France.
