The History and Topography of the County of Clare by James Frost Part I. Topography of Thomond Chapter 3. Burren, or Corcomroe East
In a battle fought in 1267 between Conor O’Brien and Conor Carrach O’Loghlen, at a place called Suidaine, O’Brien was slain and his body was laid in Corcomroe Abbey under a beautifully sculptured monument surmounted by his effigy, still in good preservation

From the Annals of Innishfallen. "A.D. 1267. An army was lead by Conor na Siudaine, the son of Donogh Cairbreach O'Brien, to Kinel-Fearmaic, where they were joined by O'Dea and O'Hehir at the head of their forces. They went to the upper Canthred to bring the inhabitants thereof to submission, and they burned the Country north of Duibh-Gleann, and proceeded northwards to Béal-Clogaidh, near the sea, where they were met by Conor Carrach O'Loughlin and his allies and a Battle ensued in which Conor na Siudaine O'Brien together with a great many of his people were slain by O'Loughlin and the race of O'Donnell Conachtach O'Brien, and he (Conor na Siudaine) was buried by the monks in the Abbey of Burren." A monument was raised over his grave by the Monks and it can still be seen to-day in the Choir of the Abbey, just to the left of where the person is standing in the above picture.

Donogh Cairbreach was succeeded by his son Conor, and in 1250 he got a renewal of the lease of the lands rented by his father for a fine of 2,200 marks and an annual rent of £200. However by this time, the O'Brien tenure of Thomond had become very insecure, as in 1248 King Henry III granted the cantred of Tradaree to Robert de Muscregos, while in 1252 the cantred of the Isles (including Clonroad) was granted to John Fitzgeoffrey, the justiciar. Robert de Muscregos pursued his claim vigorously and immediately set about colonising Tradaree, building castles at Bunratty and Clare Castle. He also got the right in 1252 to establish fairs and weekly markets at these centres.

The fortresses at Clare Castle and Bunratty posed a strong threat to O'Brien power in Clare, being so close to Clonroad. So King Conor, urged on by his fiery son Teig, turned against the Anglo-Normans in 1257 and slaughtered many of the settlers, however the fortresses remained. De Muscregos had died in 1254 but his son John continued the settlement despite O'Brien opposition. King Conor O'Brien opposed the Norman settlers up to the time of his death in 1268, when he was succeeded by his younger brother Brian Rua.
