Clann Taidg

It consisted of the parishes of Athenry, Monivea, Tiaquin, Kilkerrin, Moylough, Killererin, Ballynakill-Aghiart (in Killian), Kilmoylan, and possibly Abbeyknockmoy.

Clann Taidg seems to have come into existence during a wave of expansion by the Uí Briúin, specifically in the reign of King Tadg of Connacht (925-956).

The area, previously part of Uí Briúin Seóla, was called after the sept who are believed to have become its lords sometime in the mid-eleventh century.

However, by the end of the twelfth century it was said to have been seized by Donn Cathaig Mór Mac Airechtaig of Síl Muiredaig.

Adrian Martyn notes that "an Teaghlaigh," meaning "of the household," denotes that Clann Taidg were "hereditary marshalls to their cousins, the kings of Connacht."
