This connection suggests that the name may have initially been used to distinguish the firstborn son or heir within a family.

In the early days, the name was primarily concentrated in the regions of Normandy and Brittany in northern France. Historical records from the 11th and 12th centuries showcase variations in the spelling, such as Ainsne, Ainsney, and Aine, reflecting the evolution of the name over time.

One of the earliest known references to the name AIN can be found in the Domesday Book, a comprehensive survey of landholdings commissioned by William the Conqueror in 1086. The record includes entries for individuals bearing the name, indicating their presence in England following the Norman Conquest.
