Murtough O'Conor Faly (k. 1305)

✓ Murtough (Muirchertach) O'Conor Faly, Lord of Offaly, killed in 1305 by Sir Piers Bermingham (Mac Feorais) 'by means of treachery and deceit' in Bermingham's own castle at Carbury, co. Kildare, together with his brother Maelmora, Calvagh O'Conor and 'twenty-nine of the chiefs of his people' (AFM 1305.1; Annals of Connacht 1305.2 names Carbury Castle). The Carbury massacre (traditionally at a Trinity Sunday feast) was one of the outrages cited against the English in the Remonstrance of the Irish princes to Pope John XXII (1317). The king-lists give him as 'Muirchertach mac Muirchertaig', but no annal seen names his father - TOP.
