Donough Cairbreach O'Brien

O'Brien, Donough Cairbreach, King of Munster, was upon the deposition of his brother, in 1208, allowed by the Anglo-Normans to succeed him, and submitting to King John, Thomond was conferred, on him and his heirs, with the fortress and lordship of Garrigogonnell, which had belonged to William de Braosa. Donough fixed his residence at Clonroad, near Ennis, and commenced the erection of the beautiful Franciscan abbey, the ruins of which still remain. He was engaged in constant wars with the princes of Connaught. His death took place in 1242.
