Allaire (surname)

The Breton toponymic origin of the surname Allaire is described by Francis Gourvil in his publication Noms de famille bretons d'origine toponymique. ^[2] This would point to Allaire, a commune located in the Morbihan department.

Other Breton toponymic connections include lieux-dits "Ville-Allaire" in the communes of Langouet (Ille-et-Vilaine) and Illifaut (Côtes-d'Armor).^[3][4]

Two other possible etymologies can be traced:

• Variant form of Hilaire, French form of Latin Hilarius, derived from Latin hilaris meaning "joyful".^[5][6]
• In Brittany can be given after saint Aloire (Latin: Alorus), bishop of Quimper, Brittany.^[7]

• Alair, Aler, Alere, Allair, Allayre, Allere, Alarius
• Dallaire (e.g. Roméo Dallaire), Delair, Deller
• Halair, Haler
