Here we have the second attempt within fifteen years on the part of the Irish to determine the sovereignty under which they were to live. There was a third attempt, in 1314, after the battle of Bannockburn, when Domhnall, son of Brian O'Neill, with other Irish princes, offered the sovereignty of Ireland to Robert Bruce, and, at his instance, chose his brother Edward to be king of Ireland. A rapid survey of events will enable us to trace the development of the Irish resistance from these beginnings. We shall see the extension of Irish rule over territories once in Feudal occupation, the destruction or reduction of Feudal castles, the building of castles by the Irish, the spread of the galloglass organisation, the renewal of distinctive elements of national life. Since the immigration of Hebridean soldiers was continuous for about three centuries, so as to form a considerable new element in the population of Ireland, and since their descendants are numerous among us to-day, I shall put in a word here about the principal families that reached Ireland in this way. In Tir Conaill, the leaders of galloglasses belonged to the family of MacSuibhne, englished MacSweeny or Sweeny. In Tir Eoghain, MacDomhnaill (englished MacDonnell and MacConnell), MacRuaidhri (englished MacRory and Rogers), and MacDubhghaill (englished MacDugall in Scotland, MacDowell and Doyle and Coyle in Ireland). These three families are descended from Sumarlidi, first king of Argyle and the Hebrides. In Connacht, MacDomhnaill, MacRuaidhri and MacSuibhne. In Munster, MacSuibhne and MacSithigh (englished MacSheehy, Sheehy, and Shee). This family is a branch of the MacDonnell family. In Leinster, MacDomhnaill. In Oriel, MacCába, "MacCabe." Of galloglass commanders on record, those of the race of Sumarlidi far outnumber all the rest together. The galloglass chiefs obtained grants of land for their support. About a fourth of the whole territory of Tir Conaill was held by the three MacSuibhnes. Besides these principal names, many less prominent surnames, especially in Ulster, are of galloglass origin. The events hereinafter related are drawn from the Annals of Ulster mainly. In 1264, the year after Hakon's death, Aodh Buidhe O'Neill, who succeeded Brian as king of Tir Eoghain, extended his sovereignty over Oriel. After his time, the kings of Tir Eoghain take the title of kings of Ulster. 1265. The kings of Connacht and Tir Conaill join forces and destroy the castle of Sligo. 1267. Murchadh MacSuibhne is captured by the Earl of Ulster and dies in prison. He is the first of his surname in the Irish record. 1269. Roscommon castle built by the viceroy D'Ufford, and Sligo Castle rebuilt.
