[6] He may at one time have been partly identical with Dáire mac Degad,[7] father of Cú Roí, although traditions concerning him or them appear to have diverged at an early period, following regional paths.
[8][9] In fact in one manuscript, as Dairi Sirchrechtaig, he is listed as the father of Cú Roí,[10] and through him an ancestor of Fiatach Finn, a quo the Dál Fiatach of Ulster, son of Fuirme mac Con Roí.
T. F. O'Rahilly saw even less distinction between these figures, stating that "Cú Roí and Dáire are ultimately one and the same".
[11] Eochaid Étgudach, a High King of Ireland, was another son of Dáire Doimthech, apparently misplaced chronologically by medieval scholars.
He may be listed, if chronologically misplaced, as Dáire Drechlethan in the Baile Chuinn Chétchathaig.
[12] Despite his prominence as an ancestral figure, little is recalled in Irish legend of Dáire's reign.
However, it appears to have been remembered as strong, and in this way is typical for the Dáirine in legend, and as they were portrayed by later historians and storytellers.
A passage of poetry in the Old Irish Scéla Mosauluim[13] is translated by Kuno Meyer:[6] Dáre Doimthech dealt a draught of blood upon every stream,so that he left his stories of kingship without concealment.Dáre Doimthech was king over Brug; 'tis he ... from Srub Cermna to Srub Brain,from the western ocean to the sea in the east.alternative translation:[14] Dáre Doimthech poured outa draught of blood on every [battle-]rankso that he left conspicuous [after him]the chronicles(?)
of his reign.Dáre was king over the settled land of Éber's island- ploughing after feats of valour-from Dún (?)
Cermna to Srúb Brain,from the western ocean to the eastern sea.Daire Doimthech's five sons, to wit, the five Lugaids.
Thereafter the fawn entered the assembly, and the men of Erin together with Dáire's sons, pursued it till they reached Benn Étair.
Lugaid went to his brothers and brings them to the house; and there they get the freshest of food and the oldest of ale, and self-moving drinking-horns pouring out to them.
"Lugaid Corb ('corruption') shall be thy name, for corrupted is what thou hast consumed".
'Tis then they were seen of his brothers, with a purple garment over the damsel and Lugaid, and golden-yellow hair upon her; and she was the most loveable of women.
Thus were Dáire's sons on the morrow: on a level, houseless plain—with their hounds asleep, fastened to their spears.
