The History of Ireland (Geoffrey Keating), Volume 3

pp. 51-55 Tuathal Maol Garbh, son of Cormac Caoch, son of Cairbre, son of Niall [Naoighiallach], held the sovereignty of Ireland thirteen years. He is called Tuathal Maol Garbh (‘bald-rough’), for Comain, daughter of Dall Bronach, was his mother, and when she gave birth to Tuathal, she struck his head against a stone as a ceremony foreboding success for him, and the stone made a hollow in his head, and no hair grew in that hollow; hence he was called Tuathal Maol Garbh. … His head fell off Abacuc at the fair of Taillte, for having sworn falsely by the hand of Ciaran; and he lived thus headless four years amongst the monks. … Tuathal Maol Garbh, king of Ireland, was slain by Maol Mor, uterine brother to Diarmaid, son of Fearghus Ceirrbheoil, in Greallach Eilte. … Diarmaid, son of Fearghus Ceirrbheoil, son of Conall Creamhthainne, son of Niall Naoighiallach, of the race of Eireamhon, held the sovereignty of Ireland twenty-two years.

p. 73 Diarmaid, son of Fearghus Ceirrbheoil, king of Ireland, was slain at Raith Bheag, in Magh Line, by Aodh Dubh, son of Suibhne Aruidhe; and his head was brought to Cluain Mic Nois, and his body was buried at Cuinnire.

pp. 87-89 The cause of the Battle of Cuil Dreimhne, according to the old book called Uidhir Chiarain, was this: Diarmaid, son of Fearghus Ceirrbheoil, king of Ireland, held a Feis of Tara, and a nobleman was slain at that feis by Cuarnan, son of Aodh, son of Eochaidh Tiormcharna; and the reason why Diarmaid slew this Cuarnan was that he had slain the nobleman at the feis in violation of the law and sanctuary of the feis. And before Cuarnan was slain he put himself under the protection of the two sons of Mac Earca, to wit, Fearghus and Domhnall, and they put him under the protection of Columcille, and Diarmaid slew him in violation of Columcille’s protection for having transgressed the law of Tara, and the result of this was that Columcille assembled clanna Neill of the north (on account of his own protection and that of the children of Mac Earca having been violated), and the Battle of Cuil Dreimhne was fought against Diarmaid and the men of Connaught, and they were defeated through the prayer to Columcille.

p. 111 Conall son of Suibhne defeated in battle the three Aodhs in one day, namely, Aodh Slaine, and Aodh Buidhe, king of Ui Maine, and Aodh Roin, king of Ui bhFailghe. It was at Bruighean da Choga he defeated them.

pp. 115-117 Aodh Slaine, son of Diarmaid, son of Fearghus Ceirrbheoil, and Colman Rimhidh, son of Muircheartach Mac Earca, held the sovereignty of Ireland. They were six years in joint sovereignty. Mughainn, daughter of Cucharainn, son of Duach, was the mother of Aodh Slaine. … He was called Aodh Slaine, for it was on the river which is named Slaine he was born. … Aodh Slaine was slain by Conall Guithbhinn, son of Suibhne.
