Uí Liatháin

[1] The two have been given various origins among both the early or proto-Eóganachta and among the Érainn or Dáirine by different scholars working in a number of traditions, with no agreement ever reached or appearing reachable.

The Déisi Muman lived adjacent to them in the neighbouring County Waterford and the Laigin could be found not much farther east in the Kingdom of Leinster.

Ruithchern, daughter of the King of Iarmuman (and possibly Munster), Áed Bennán mac Crimthainn, and sister of Mór Muman, was taken captive by the Uí Liatháin and forced to herd sheep.

[15][16] At the Battle of Carn Conaill, the Uí Liatháin are listed among the Munster allies of Guaire Aidne mac Colmáin, a mention dismissed by Byrne,[17] but discussed at length by Seán Ó Coileáin,[18][19] who relates it to the cycle of Mór Muman and Ruithchern.

A substantial part of the recently defunct kingdom was granted to the De Barry family by John of England in 1206, although the Uí Meic Tire persisted in a southern outpost for a few decades following.
