 * M1386.7. O'Conor Roe, with all the Connacians he could find to join him, went to assist Mac William Burke against Donnell, the son of Murtough O'Conor Sligo, and the Clann-Donough. They carried off great preys from Tir-Fiachrach Muaidhe. After this they proceeded to Clanrickard on a predatory excursion. O'Brien, with a great army, and Mac William of Clanrickard, came up with them; but O'Conor Roe turned round on them, and defeated them; and Conor, the son of Teige, son of Conor O'Brien, was slain in the conflict.
 * M1386.11. A peace was made by the Connacians with one another after the war, and Mac William Burke went into the house of Mac William of Clanrickard, and ceded to him the lordship. Mac Feorais Bermingham went into his house in like manner.
