Uí Bairrche
Uí Bairrche (Modern Irish: Uí Bhairrche, pronounced [iː ˈwaːɾˠəçə]) was an Irish kin-based group that originally held lands in the south of the ancient province of Leinster (or Cóiced Laigen "the Fifth of the Laigin"). Another south Leinster kin group associated with the Uí Bairrche were groups of the Fothairt.
