The Irish already had a system for creating hereditary surnames established when the followers of Strongbow settled in eastern Ireland. Although there was relatively little friction between the two systems because they operated according to very similar principles, the Strongbownians frequently used local surnames. In Ireland, local surnames were almost unheard of, but in England they were probably the most common form of hereditary surname. Local surnames, such as De courcy, were taken from the name of a place or a geographical feature where the person lived, held land, or was born. The surname De courcy is derived from in the settlement of Coursi in Normandy. The surname De courcy belongs to the large category of Anglo-Norman habitation names, which are derived from pre-existing names for towns, villages, parishes, or farmsteads. The Gaelic form of the surname De courcy is de Cúrsa.

Descended was Balderic Teutonicus, Earl of Brion in Normandy, who had six sons. The third son was Robert de Courcy, Lord of Courcy in Normandy. His son, Richard, was at the Battle of Hastings in 1066 A.D. and was granted Stoke-Courcy in Somerset, and other lands.

Hunger and disease took the lives of many Irish people and many more chose to leave their homeland to escape the horrific conditions.

For those families that survived the journey, all three of these things were often attained through much hard work and perseverance.

The De courcy 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: Vincit omnia veritas
Motto Translation: Truth conquers all things.
