Donnchadh mac Murchada

Donnchad mac Murchada (aka 'Donnchadh Ua Mael-na-mbo' and 'Donnchad grandson of Mael na mBó'; Leinster, 1065 - 8 December 1115) was a King of Leinster and Dublin from 1098 until 1115 when he died in battle while fighting Domnall Gerrlámhach, the King of Dublin, and the Danes. A near contemporary account by Gerald of Wales, suggests that the King of Dublin lured him to Dublin under false pretence of peace, killed him and then buried him with a dog as an insult. "A battle was gained by Domhnall mac Briain and the foreigners of Ath-cliath over the Leinstermen, wherein fell Donnchadh mac Mael-na-mbo, lord of Ui-Ceinnsealaigh, and Conchobhair mac Conchobhair, lord of Ui-Failghe, with his sons, and many others besides them." [Annals of the Four Masters, Vol 2. p. 1001]

He was the third son of Murchad mac Diarmuid, King of Leinster, and Sadb MacBricc.

He married an unknown wife and Orlaith ingen O'Braenain (Dublin, 1090-?), daughter of Gilla Michil Cinaed O'Braenain (Dublin, 1053-?) and wife (1078) Uchdelb O'Gairbita (1058-?), daughter of Cearnachen O'Gairbita (1040-?), King of Uí Feilmeda (Ban Senchus 193, 198, 231.), and had two sons by first marriage, Enna Mac Murchada (?-1126), King of Leinster in 1117 (some lineages do not show Enna as in line), and Murchad Mac Murchada (?-1172), King of Osraige between 1123 and 1126, deposed, and one son by second marriage, Diarmait Mac Murchada, King of Leinster.
