Show ContentsLascy 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 Lascy. 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 Lascy 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 Lascy is de Léis. However, there is a native Irish family of County Wexford named Ó Laitheasa who anglicize their surname as Lascy. 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 Lascy family

The surname Lascy 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.

Migration of the Lascy family

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 Lascy: John Lacey, who settled in Virginia in 1677; Elizabeth Lacey with her husband James and son and daughter settled in Georgia in 1737; William Lacy settled in Virginia in 1635.



The Lascy 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.
