Origin of the O'Sullivan Clan Name
The name O'Sullivan is derived from the irish term meaning “one eye”, O Suilleabháin meaning one-eyed man. There origins are illustrious as they are descended from Eoghan Mor, father of Oilioll Olum and together with the McCarthys, O'Keeffes and O'Callaghans became the leading familiesof the Munster Eoganachta.
They originally inhabited the areas of Cahir in County Tipperary but today they are mainly found in Cork, Kerry and Limerick. When the Normans arrived in Ireland many clans were forced to retreat west as their homelands became parts of the new Norman or Anglo-Irish territories. In 1192 this happened to the O'Sullivans and they were forced into the territory of the O'Driscolls, whom they drove inot the sea and the Beara peninsula.
Today it remains one of the most popular surnames in Ireland and is third after Kelly and Murphy. The O'Sullivans are still living in their ancient homeland in counties Cork, Kerry and some in Limerick.
There are more than 200,000 carriers of the name Sullivan in the United States.
