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

The surname Lasswell 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 Lasswell migration to the United States +

During the middle of the 19th century, Irish families often experienced extreme poverty and racial discrimination in their own homeland under English rule. Record numbers died of disease and starvation and many others, deciding against such a fate, boarded ships bound for North America. The largest influx of Irish settlers occurred with Great Potato Famine of the late 1840s. Unfortunately, many of those Irish that arrived in Canada or the United States still experienced economic and racial discrimination. Although often maligned, these Irish people were essential to the rapid development of these countries because they provided the cheap labor required for the many canals, roads, railways, and other projects required for strong national infrastructures. Eventually the Irish went on to make contributions in the less backbreaking and more intellectual arenas of commerce, education, and the arts.

The Lasswell 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.
