Con O'Donnell Son of Niall Garv, son of Turlough-an-Fhina O'Donnell 1460 Mac Manus of Tir-Tuathail, Rory, the son of Owen Roe Mac Manus, fully worthy to be Lord of that territory, was slain by Con and Teige, the son of Teige O'Rourke, while in pursuit of the spoils of the territory. O'Donnells people carried the spoils with them to Airged-glenn (between Co's Sligo and Leitrim); but, after the killing of Mac Manus, the chiefs of the Clann-Manus deprived them of their preys in that valley. AFM 1461 The sons of Niall Garv O'Donnell, Hugh Roe, Con, and Owen, assembled all their forces, and proceeded into Fanad to the son of Mac Sweeny, Mulmurry, because Turlough Cairbreach O'Donnell was wreaking his animosities on the son of Mac Sweeny and all Fanad, for their friendship to the sons of Niall. The sons of Niall and the son of Mac Sweeny held a council, to consider how they should act, in order to defend themselves against the sons of Naghtan and their forces, who were ready to wreak their vengance and emnity on them. When O'Donnell and the sons of Naghtan were informed that the sons of Niall had arrived in Fanad he set out after them with his brothers, his troops and a battalion of Scotsmen then in his service, and pitched his camp at Ceann-Maghair, to watch and check the sons of Niall O'Donnell and Mulnurry Mac Sweeny, who was passing with them out of the territory. The sons of Niall and the people of Fanad having heard of this, they consulted with one another; and they came to a determination not to abandon or cede the pass to any host or army that should oppose them: and when this resolution was adopted, the sons of Niall, Mulmurry Mac Sweeny, Owen Bacagh Mac Sweeny, and all the people of Fanad who adhered to them, proceeded to Ceann-Maghair (Kinnaweer, Kilmacrenan, Co Donegal) to meet and oppose the forces of O'Donnell and the sons of Naghtan; and as they approached each other, they did not hesitate to attack each other, in consequence of their enmities and hatred, provocations and animosities; and they met each other in a furious and obstinate battle, in which Turlough Cairbreach and the sons of Naghtan were defeated. O'Donnell himself was taken prisoner and his brother, Manus, and numbers of others, were slain. Turlough Cairbreach was afterwards maimed (to make him unfit for the chieftainship, one of his hands and one of his feet were cut off). After this defeat at Ceann-Maghair, these victorious chieftains went to Cill-Mic-Nenain (Kilmacrenan), and Hugh Poe, the son of Niall Garv, was styled lord after the lawful manner; and he called Mulmurry Mac Sweent the Mac Sweeny Fanad. AFM 1464 Con, the son of Naill Garv O'Donnell was slain by Egneghan, the son of Naghtan O'Donnell, at Findrum, Convoy, Raphoe, Co Donegal, on the 8th day of May. AFM
