The Conmhaícne or Conmaicne were a people of early Ireland, perhaps related to the Laigin, who dispersed to various parts of Ireland. They settled in Connacht and Longford, giving their name to several Conmaicne territories. T. F. O'Rahilly's assertion the Conmaicne were non-Goidelic is not widely accepted.

Etymology[]

Their name supposedly originates from a mythical ancestor known as Conmac, descended from Fergus mac Roich and Queen Maeve of Connacht. However, Walsh stated, "Conmac son of Fergus is a genealogical fiction". the word Conmacne means "progeny of Conmac" (ne, a progeny). Conmac itself means "hound-son" (con, hound; mac, son).

Branches[]

Branches of the Conmaicne dispersed to various places.

John O'Donovan wrote:

"The chief families of the Conmacians were the O'Fearralls, princes and lords of Annaly, or Longford; the Mac rannalls, a name anglicised to Reynolds, who were Lords of Conmaincee of Moy-Rein and Muintir-Eolais, in Leitrim; the Mac Keoghes, who were chiefs in Galway, and also in Lenister; the MacShanleys; O'Rodaghans; MacDorchys; O'Mulveys; O'Morans, and O'Mannings, chiefs and clans in various parts of Longford, Leitrim, and Roscommon".
