Show ContentsLasie History, Family Crest & Coats of Arms

Ireland already had an established system of hereditary surnames when the Strongbownians arrived. Often the two traditions blended together quite well due to some of their basic similarities, but the incoming Anglo-Norman system brought in some forms that were uncommon amongst the Irish. One of these Anglo-Norman anomalies was the prevalence of local surnames, such as Lasie. Local names were taken from the names of a place or a geographical feature where the person lived, held land, or was born. Originally, the 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 local surnames of these Strongbownian invaders referred to places in Normandy, or more typically England, but eventually for those Anglo-Normans that remained in Ireland, the nicknames referred to places or geographical features of the island: they became true local names. The Lasie family appears to have originally lived in the settlement of Lassy in the region called Calvados in northern France. The name of this place is derived from the Gaulish personal name Lascius, which is of uncertain origin, and the local suffix -acum. The Gaelic form of the surname Lasie is de Léis. However, there is a native Irish family of County Wexford named Ó Laitheasa who anglicize their surname as Lasie. This name, which was originally Ó Flaithgheasa, is derived from the Gaelic word flaith, which means prince. 1 This was, in most cases, a nickname applied to someone with princely manners or a regal bearing.

Early Origins of the Lasie family

The surname Lasie was first found in County Limerick (Irish: Luimneach) located in Southwestern Ireland, in the province of Munster, where they had been granted lands by Strongbow after the invasion of Ireland in 1172.

United States Lasie migration to the United States +

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 Lasie:

The Lasie 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: Meritas augentur honores
Motto Translation: Honours are enhanced by deserts.
