[1] MacMorough: The ancient kings of Leinster had fortresses or royal residences at Dinnrigh, near the river Barrow, between Carlow and Leighlin; at Naas, in Kildare; and in after-times at the city of Ferns in Wexford, which was their capital; and also at Old Ross in Wexford; and at Ballymoon in Carlow. The MacMoroughs were inaugurated as kings of Leinster at a place called Cnoc-an-Bhogha, attended by O'Nolan, who was the King's Marshal, and Chief of Forth in Carlow; by O'Doran, Chief Brehon of Leinster; and by MacKeogh, his Chief Bard; and the MacMoroughs maintained their independence, and held the title of "Kings of Leinster," with large possessions in Wexford and Carlow down to the reign of Queen Elizabeth. The Hy-Cavanagh or O'Cavanaghs were chiefs of the ancient territory which now comprises the barony of Idrone East, in the county Carlow; and in modern times became the representatives of the MacMoroughs, Kings of Leinster.

[2] Boromha: For the explanation of this tribute, see the Paper "Ancient Leinster Tributes," in the Appendix.

[3] Murcha: We have seen it stated in a Genealogical Chart in one of the Kilkenny Arch. Journals, that the Clan-Morochoe descended, and derived their name, from this Murcha; but MacFirbis distinctly states that the Clan-Morochoe is descended and takes its name from Murcha, who is No. 111 on this pedigree.

[4] MacMorough: In 1153 Dermod MacMorough carried off Dearvolga, daughter of O'Melaghlin, the last King of Meath, and the wife of O'Ruark, Prince of Brefney. On this subject Webb writes:—"The transaction cannot have had much of the romance usually associated with the idea of an elopement. She was forty-four years of age, and did not leave her lord without carrying off her cattle and furniture. This was fifteen years before Dermot sought Anglo-Norman assistance; so that the invasion (of Ireland) can scarcely be attributable to the elopement. . . . Dearvorgal spent much of her later life in religious exercises, and part of her substance in endowing churches. She survived until 1193, when she died at Mellifont Abbey, county of Meath, which she had enriched with many presents. Although Dermot's Kingdom nominally passed into Earl Strongbow's family after his decease, much of it appears to have been soon again occupied by the MacMurroughs, by whom it was held in almost undisputed sway for several centuries."
