Donnchadh mac Murchada

Donnchad mac Murchada 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."
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, daughter of Gilla Michil Cinaed O'Braenain and wife Uchdelb O'Gairbita, daughter of Cearnachen O'Gairbita, King of Uí Feilmeda, and had two sons by first marriage, Enna Mac Murchada, King of Leinster in 1117, and Murchad Mac Murchada, King of Osraige between 1123 and 1126, deposed, and one son by second marriage, Diarmait Mac Murchada, King of Leinster.
