All of those who were involved in his latest success had been from the Dal Cuinn northern Ui Niaill, as the Dal Cuinn southern Ui Niaill had previously already gained the authority over the Septs in the Leinster Province. His personal victory had only added to the authority of all the Ui Niaill Septs to now claim the High Kingship of Ireland outright. *99.Aedh Allan the Dal Cuinn northern Ui Niaill Cenel nEogain 160th King of Ireland was killed in the Battle of Magh Seirigh at Ceanannus Mor (Kells) between the two Tethbas by *100.Donnell / Domhnall Midi - of Meath the Dal Cuinn southern Ui Niaill Clann Cholmain 16th King of Meath, the son of 99.Murrough / Murchadh Midi the previous 14th King of Meath.
