The territory of Cairbre Ui Chiardha was co-extensive with the present barony of Carbury in the north-west of the county of Kildare. After the subjugation of the O'Ciardhas their country became the possession of a branch of the Berminghams. Conell Mageoghegan, in his translation of the Annals of Clonmacnoise (made in 1627), ad. ann. 1076, says, that Carbrey O'Kiergie was in his own time called 'Bremyngham's country'. See Genealogies, Tribes, and Customs of Hy-Fiachrach, p. 475.
