Aymer is of Old French origin, derived from the Germanic elements 'adhel' meaning noble and 'hari' meaning army. It was introduced to England by the Normans after the Norman Conquest in 1066. The name gained popularity during the Middle Ages and was often used as a given name and title among the nobility of that period. Aymer is also associated with several saints in the Catholic Church, which may have contributed to its usage. Today, it is still considered a unique and historic choice for a first name.
