Part I. Topography of Thomond Chapter 10. Ui Toirdhealbhaigh

Ui Toirdhealbhaigh

In the topographical account of this country by O’Heerin, Ui Toirdhealbhaigh is described as lying about Killaloe; and that it was co-extensive with the parishes of Killaloe, O’Briensbridge, and Kiltenanlea is very probable. It was bounded on the north by Ui Congaile, on the east and south by the Shannon, and on the west by Gleann Omra. In the Annals of the Four Masters, it is called Magh Ua Toirdhealbhaigh, that is to say the plain of Turlogh, from whom Brian Boroimhe was eighth in descent. It appears to have been the original patrimony of the O’Briens before they became powerful, and spread themselves over most parts of Thomond, and over various extensive districts in Tipperary, Limerick, and Cork.
