What is "dairine"

The Dáirine (Dárine, Dáirfine, Dáirfhine, Dárfine, Dárinne, Dairinne), later known dynastically as the Corcu Loígde, were the proto-historical rulers of Munster before the rise of the Eóganachta in the 7th century AD. They appear to have derived from the Darini of Ptolemy and to have been related to the Ulaid and Dál Riata of Ulster and Scotland. In support of this, their ancestors appear frequently in the Ulster Cycle, where they are known as the Clanna Dedad, and are the killers of Cú Chulainn. All are considered Érainn (see also O'Rahilly's historical model). In historical times the Dáirine were represented, as stated, by the Corcu Loígde, and probably by the Uí Fidgenti and Uí Liatháin, as well as a few other early historical kindreds of both Munster and Ulster. In ancient genealogical schemes, the historical Dál Fiatach of Ulaid also belong to the Dáirine (Clanna Dedad).
