* ''M1461.12. An army was led by Mac William Burke and his kinsmen into Machaire-Chonnacht, to release Felim Finn from the son of Brian Ballagh; and they gave him his own demand for his ransom, and the chiefs of Connaught as guarantees for the payment of it, whereupon Felim was set at liberty. He took those chieftains with him to Carn-fraoigh-mhic-Fiodhaigh-foltruaidh; and Mac Dermot put on his shoe, after having purchased him; and they obtained the hostages of the descendants of Ona, the son of Aengus, and those of the Hy-Briuin. Mac Williain left these hostages with the son of Brian Ballagh, and returned home. As soon as the sons of O'Conor Roe had heard of this, they ransomed Teige O'Conor from O'Conor Don, by giving the half townland of Baile-an-chlair for him; and they afterwards went over to Conor Mac Branan.'' * ''M1463.7. William Burke, the son of Richard, marched to attack the castle of Muilenn-Adam, in revenge of the loss of his eye. He was pursued to the borders of Ballymote, where he turned round on his pursuers, and killed fifteen of them, with the son of Manus, son of Dermot Mac Donough, and with the sons of O'Neill, who had some time before put his eye out at that castle.'' * ''M1464.24. O'Donnell, Mac William Burke, and many of the Irish and English of Ireland, repaired to Dublin to meet Thomas, Earl of Desmond, at that time Lord Chief Justice of Ireland, and entered into a league of friendship and fealty with him.'' * ''M1466.8. William, son of Walter Burke, and William Burke, son of John, the son of Mac Walter, died.'' * ''M1467.19. O'Kelly and the sons of William Burke were defeated at CrosMoighe-Croin, by Mac William of Clanrickard, and by the O'Briens. William Caech Burke, the son of Mac William, two sons of O'Kelly, Hugh Boy, son of Turlough Mac Donnell, Constable of their Gallowglasses, and ten of the gentlemen of the Clann-Donnell who were along with him, were slain in the conflict. One hundred and sixty gallowglasses, and numbers of others, were also slain. O'Donnell i.e. Hugh Roe, son of Niall Garv, went to Connaught, to take revenge for this defeat, for Mac William and O'Kelly were his friends and confederates. He forced the Clanrickards to make peace, and then returned home in safety.'' * ''M1468.21. Richard Burke went to Moylurg, and made peace with Mac Dermot; and both set out to oppose O'Donnell, but before they could arrive at where he was, he had crossed the Erne, so that they did not meet one another on this occasion. Richard returned to Machaire-Chonnacht, and took hostages from the sons of O'Conor Roe; and he made prisoners of the descendants of Felim, because they would not consent to give him hostages.'' * ''M1469.18.
