Cairpre Gabra

Between the 5th and 12th centuries, an Irish sept claiming descent from Coirpre mac Néill ruled a barony of north Tethbae,[n 1] called Cairpre Gabra.

[2] Tradition claims Coirpre married a Fir Bolg princess named Mulreany and ruled all of North Longford from the Moat of Granard.

[8] Ó Duígeannáin stated Cairbre Gabhra is identical to the ancient place "Ciarbre Ua gCiardha" disagreeing with O'Donovan's identification as "Carbury (County Kildare barony)".

[17] It is generally believed a larger Cairpre grouping stretched from Sligo to Longford at an early date taking in Leitrim and parts of Fermanagh (Tuatha Ratha or Magheraboy) and it was divided in two by the expansion of the Kingdom of Breifne under the Uí Briúin.

[20] The north-western frontier ran from Cluain Cusa (Clooncoose) through Crott (between Slieve Carbry and Lake Naback) over as far as Lough Gowna, but excluded the most northern portion of the modern barony of Granard.

[23] It is believed a section of the dynasty were introduced as lords of Carbury in Kildare in a 12th-century intrusion following this pressure on their original territory in north-east Longford.
