 The family fell out with the de Burghs later and were divested of their Connacht lands.This weakening of the Norman colony in Carbury and Sligo allowed the Clann Aindrias the space to establish the Lordship of Iochtar Connacht (Lower Connacht) in the wake of the Burke Civil War from their base, Caislen-conor in Fassacoille, now Bradcullen in the townland of Urlar.Lines of the original Cenel Cairbre Drom Cliabh survived quasi-anglicised as 'Stone' (from O'Mulclohy) in Carbury and the O'Flanagan's of Tuatha Ratha, in the barony of Magheraboy, Fermanagh.
