Show ContentsLenihan History, Family Crest & Coats of Arms

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 Lenihan, 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 Lenihan family originally lived in the settlement of Llanaghan, which is in the Welsh county of Brecon.

Early Origins of the Lenihan family

The surname Lenihan was first found in County Roscommon (Irish: Ros Comáin) located in central Ireland in the province of Connacht, where they were granted lands by Strongbow after his invasion of Ireland in 1172.

Lenihan migration to the United States +

The Irish emigration during the late 18th and 19th century contributed to the melting pot of nationalities in North America, and the building of a whole new era of industry and commerce in what was seen as a rich, new land. Ireland'sGreat Potato Famine resulted in the worst economic and social conditions in the island's history. And in response to the hunger, disease, and poverty, during this decade the total number of emigrants to leave for North America rivaled all the previous years combined. Those from this decade that arrived on North American shores were not warmly welcomed by the established population, but they were vital to the rapid development of the industry, agriculture, and infrastructure of the infant nations of the United States and what would become Canada. Research into early immigration and passenger lists has shown many people bearing the name Lenihan:

The Lenihan 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.
