O’Sullivan is the third most popular surname in Ireland and the most common to have reinstated the Gaelic ‘O’ prefix to the name.
The O’Sullivans originally come from the Munster region of Ireland. They are descended from Eoghan Mor, whose son Olioll Olum was the King of Munster in the 3rd century.
Eoghan Mor is also an ancestor of the MacCarthys, O’Keeffes and O’Callaghans.
Dark eyed or one eyed?
The name O’Sullivan derives from O’Sileabhin. The word ‘sil’ means eye and scholars believe that O’Sileabhin means either ‘one eyed’, ‘dark eyed’ or ‘hawk eyed’.
In the 1100s, the O’Sileabhins were Lords in Cahir, County Tipperary. They later split into two septs and spread further afield. The O’Sullivan Mor sept settled in what is now South Kerry and the O’Sullivan Beare went to West Cork.
The motto on the O’Sullivan coat of arms reads ‘Lam Foisteanac Abu’ which means ‘The steady hand to victory’.
Rebellion against Queen Elizabeth I
In 1602 Donal O’Sullivan Beare joined forces with the O’Neills and led his clan in the rebellion against Queen Elizabeth I. They had been supported by the King of Spain. However, Spanish general Juan del Águila, surrendered.
O’Sullivan elected to fight on and his men were under siege at Dunboy Castle, but they were able to withstand the attack.
O’Sullivan then led them 200 miles to safety in the territory of his allies, the O’Rourkes. Many of the men died of starvation or in battles during the journey but O’Sullivan is still seen as a hero for his resistance to the Queen’s army.
He later took many of his family members to Spain after being invited by King Philip III. Many O’Sullivans served in the Spanish army and navy.
He is the first person with the name O’Sullivan to be recorded in writing. His exploits were noted in the book ‘Records of Dunboy, Bantry Bay’.
Owen Roe O’Sullivan
The poet Owen Roe O’Sullivan was born in 1748. He was a talented songwriter and poet but had to flee to England when he was caught having an affair with a married woman. He joined the British navy but regretted doing so and often tried to leave.
Despite this he was an excellent navy man and was commended for his bravery during battles with the French. Ironically, his death came in a fight, not against the French military but with servants of Captain Cronin who had been the subject of criticism in O’Sullivan’s poetry.
