Allain

Allain is a French form of the name rooted in the medieval Latin Alanus, whose ultimate origin is uncertain, though it is commonly associated with the Alans, a Sarmatian people who migrated into western Europe during the early medieval period. The name was introduced to Britain by Breton settlers following the Norman Conquest and became widely used across France and the British Isles throughout the Middle Ages. Variant forms include Alan, Allan, Allen, and the Breton Alan.
