Dáire is an Old Irish name which fell out of use at an early period, remaining restricted essentially to legendary and ancestral figures, usually male.
Both Eoin MacNeill[1] and T. F. O'Rahilly believed that most, if not all of those listed may derive from the same prehistoric or mythological figure,[2] or have adopted each other's features to such an extent as to all be composites.
The latter states that Daire and Cú Roí "are ultimately one and the same",[3] and refers to him as "the god of the Otherworld".
[6] The Darini were a population group or kingdom located by Ptolemy's 2nd century Geography in south Antrim and north Down.
[7][8] Julius Pokorny believed this to be a mistake for Darioni, from the ground form *Dārio-nion, reconstructed from the proto-historical Dairine,[9] descendants of Daire Doimthech / Daire mac Dedad and ancestors of the historical Corcu Loígde.
