The old Gaelic name used by the O'Sullivent family in Ireland was Ó Suileabhain, which is partially derived from the word "suil," which means "eye." The surname probably means either one-eyed or hawk-eyed.

Early Origins of the O'Sullivent family

The surname O'Sullivent was first found in the territory of Cahir in County Tipperary (Irish: Thiobraid Árann), established in the 13th century in South-central Ireland, in the province of Munster. The Sullivan spelling is by far the most common name in Munster, and is predominantly found in the counties of Cork and Kerry, with a smaller but still significant population in County Limerick. 1

Migration of the O'Sullivent family

North America accepted thousands of Irish immigrants during the 19th century as their homeland suffered under foreign imperialistic rule. Although settlers from the early portion of the century came to North America by choice in search of land, by far the largest influx of Irish immigrants came to North America during the Great Potato Famine of the late 1840s. Many of these Irish families left the country destitute and in some cases suffering from disease. However, those who survived the long ocean voyage were especially vital to the development of industry in the United States and what would become known as Canada. Research of immigration and passenger lists has shown many early immigrants bearing the name O'Sullivent: Andrew, Arthur, Daniel, Denis, John, Michael, Patrick, Simon, Timothy and William O'Sullivan, who all arrived in Philadelphia between 1840 and 1860; Anne, Bridget, Cornelius, Daniel, Denis, Ellen, James, Jeremiah, John, Julia, Mary, Owen, Patrick, Terence and William Sullivan all arrived in Boston in 1849.



The O'Sullivent 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: Lamh foistenach abú
Motto Translation: The steady hand to victory.
