The Anglo-Norman Conquest of Ireland lead by Strongbow introduced the first non-Gaelic elements into Irish nomenclature. These Anglo-Normans brought some traditions to Ireland that were not readily found within Gaelic system of hereditary surnames. One of the best examples of this is the local surname. Local surnames, such as Clanahan, were taken from the name of a place or a geographical feature where the person lived, held land, or was born. These surnames were very common in England, but were almost non-existent within Ireland previous to the conquest. Originally, these place names were prefixed by "de," which means "from" in French. This type of prefix was eventually either made a part of the surname, if the place name began with a vowel, or was eliminated entirely. The Clanahan family originally lived in the settlement of Llanaghan, which is in the Welsh county of Brecon.

Ireland's Great Potato Famine left the country's inhabitants in extreme poverty and starvation. Many families left their homeland for North America for the promise of work, freedom and land ownership. Although the Irish were not free of economic and racial discrimination in North America, they did contribute greatly to the rapid development of bridges, canals, roads, and railways. Eventually, they would be accepted in other areas such as commerce, education, and the arts. An examination of immigration and passenger lists revealed many bearing the name Clanahan:

The Clanahan Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Patriae infelici fidelis
Motto Translation: Faithful to an unhappy country.
