The old Gaelic name used by the O'Sullivan 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'Sullivan familyThe surname O'Sullivan 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.

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.
