Naming conventions


Sullahan

Some O'Sullivans in the midlands and south Ulster were originally ''(O) Sullahan'' (from ''Ó Súileacháin'', probably from ''súileach'', quick-eyed, according to MacLysaght). This surname has now almost entirely changed to ''Sullivan''.

Early modern period

The O'Sullivan Beare clan was further divided in 1592. When Dónal O'Sullivan, the chieftain, was slain in 1563 his son of the same name was but a child two years of age. The Irish laws of Tanistry required that the title of chieftain be passed on to the most capable of the dead chief's family. As a result, the clan decided that Owen, one of the brothers of the dead chief, would take over control of the clan and become Lord of Beare and Bantry. Owen acknowledged the English crown and was knighted by Queen Elizabeth. In 1587 Dónal, now twenty-six years old, decided to claim leadership of the clan. He petitioned the authorities in Dublin, using

as the basis for his claim, whereby the oldest son should inherit his father's title regardless of his age at the time of his father's death. The English Commission in Dublin was receptive to his argument since they preferred to have the English procedure followed throughout Ireland. In addition Sir Owen had lost influence in Dublin due to implication in the
Desmond Rebellion The Desmond Rebellions occurred in 1569–1573 and 1579–1583 in the Irish province of Munster. They were rebellions by the Earl of Desmond, the head of the Fitzmaurice/FitzGerald Dynasty in Munster, and his followers, the Geraldines an ...
. The Commission found in favor of Dónal, who was now The O'Sullivan Beare. Sir Owen had to be content with Whiddy island and part of Bantry. He died the following year and was succeeded by his son, another Sir Owen. The O'Sullivans and other clans provided shelter to 12-year-old Gerald FitzGerald when troops sought to capture him as the last heir to the Earlship of Desmond. In the late 1590s, it was the Sullivan Mor clan and their close allies the McSweenys who bore the brunt of the fighting with the English forces. Donal, however, held the O'Sullivan Beare clan, held back from the fighting until the O'Donnells and O'Neills of Ulster entered the campaign.


After 1600

By the year 1600 all of Munster was in a turmoil. As retribution for their support of the Desmond rebellion, the Munster clans lost over of their land to English settlers. When the

. Daniel O'Sullivan Mor could only contribute token support because of the losses he had sustained in the previous years. Dónal marched to Kinsale with an army of one thousand men. He sent a letter to King Philip swearing allegiance to him as his sovereign. The letter was intercepted by English agents and was later used as reason for denying him pardon. On 24 December 1601 at the coming of dawn the battle began. It was over in a matter of hours. It was a resounding defeat for the Irish forces. This was due in large part to the reluctance of the Spanish troops to leave the protection of the walled city of Kinsale and join the battle until it was over. O'Neill retreated back to Tyrone with his battered troops. O'Donnell handed over command of his soldiers to his brother and embarked for Spain to plead for more help from King Philip.

, commander of the English, was only too happy to accept his request. Aquila agreed to surrender the castles his troops were defending. This meant that the O'Sullivans and the O'Driscolls had to fight the Spanish to regain their castles. Donal O'Sullivan wrote to King Philip complaining about the behavior of Aquila. When Aquila returned to Spain he was held in contempt by King Philip and put under house arrest. Many of the O'Sullivan clan's non-combatants were sent to the island of Dursey to keep them out of harm's way. An English force led by a John Bostock attacked the small garrison guarding the island. They butchered the entire population of the island, women, children, and the garrison. They cast their bodies, some while they were still alive, onto the rocks below the cliff overlooking the sea.

, was destroyed in the Siege of Dunboy in 1602 and its garrison was put to death by hanging. Dónal O'Sullivan and approximately one thousand followers consisting of four hundred soldiers and the rest civilians began a journey to Leitrim to the castle of his friend Ó Ruairc (O'Rourke). He believed that he could hold out longer amongst his northern allies, the O'Donnells and O'Neills. Carew declared them outlaws and decreed that anyone that aided them would be dealt with as outlaws as well. Throughout the trek they were attacked by English forces and Irish that were loyal to Elizabeth. The countryside had been ravaged by war and famine; the people along the way were trying to stay alive themselves. They could ill afford to provide any aid or food. They began the march on 31 December 1602. A detailed account of the march is provided by Philip O'Sullivan Beare, a nephew of Dónal O'Sullivan.
