Note 473 — Chapter IV
Reading edition
Rom. xv. 13 (vg.).—The success of Malachy in establishing peace in the latter years of his rule at Armagh may be attributed in part to the influence of a prince who is not mentioned in the text. Donough O'Carroll first appears in the Annals as chieftain of the men of Fearnmaigh (now represented by the barony of Farney, co. Monaghan), whom he led in an expedition against Fingal (the district north of Dublin) in 1133. He seems to have succeeded to the kingdom or lordship of Oriel (which included the present counties of Armagh, Monaghan and Louth) on the death of Conor O'Loughlin (May 1136); for in 1138, "with the Oirgialla," he took part in an invasion of Meath. His career was prosperous till 1152, when he assaulted the coarb of Patrick (Gelasius). In consequence he was attacked by the Cenél Eoghain, and expelled from Oriel. In 1155 he was imprisoned by Tighernan O'Rorke in Lough Sheelan, for six weeks; but he escaped and recovered his kingdom, and was present at the consecration of the Church of Mellifont Abbey in 1157. He was murdered in 1168. For his support of Malachy see Additional Note C, p. 170.
