The Anglo-Norman invaders imported their own naming principles which supplemented the pre-existing system of hereditary surnames that the Irish had already developed. One of the most common types of surnames for both cultures at this time was the patronymic surname, which was formed from the name of the bearer's father, or another older relative. Like the Irish, the Strongbownians used prefixes to build patronymic names, and although the Gaelic prefixes of "Mac" and "O" were occasionally adopted, the Anglo-Normans also used the prefix Fitz-, which was derived from the French word fils, and ultimately from the Latin filius, which both mean son. This prefix probably originated in Flanders or Normandy, but it is now found only in Ireland. Another way of forming patronymic names was through the addition of a diminutive suffix to the given name, such as -ot, -et, -un, -in, or -el. Occasionally, two suffixes were combined to form a double diminutive, as in the combinations of -el-in, -el-ot, -in-ot, and -et-in. The surname Aillemer is derived from the Anglo-Saxon personal name Ædelmær, which literally means "noble, famous." The Gaelic form of the surname Aillemer is Aighlmear.

Early Origins of the Aillemer family

Migration of the Aillemer family

In the 1840s, Ireland experienced a mass exodus to North America due to the Great Potato Famine. These families wanted to escape from hunger and disease that was ravaging their homeland. With the promise of work, freedom and land overseas, the Irish looked upon British North America and the United States as a means of hope and prosperity. Those that survived the journey were able to achieve this through much hard work and perseverance.
