The History of Ireland (Geoffrey Keating), Volume 2

p. 367 He was called Eochaidh Muighmheadhon because, as to his head and breast, he resembled the king, and, as to his waist, he resembled a slave called Mionghadhach, and hence he was called Muighmheadhon.

pp. 411-413 Now this king is called Niall Naoighiallach from his having received nine hostages or nine captives, five of them from the provinces of Ireland, and four from Alba.

p. 413 Fearadhach was his proper name at first; and he was called Dathi, for dathi means ‘quick’; and it was because of the quickness with which he put on his armour that he was called Dathi.

The History of Ireland (Geoffrey Keating), Volume 3

p. 43 He was called Oilill Molt because of a craving for wether’s flesh that his mother Eithne, daughter of Oraidh, felt when she was pregnant with Oilill; and a lady who was with her named Fial, daughter of Eochaidh Seideadh, called him by the name of Oilill Molt after he was born.

pp. 51-53 He is called Tuathal Maol Garbh, 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.

p. 115 He was called Aodh Slaine, for it was on the river which is named Slaine he was born.
