)[3][4][5] There is some dispute in the sources as to his reign and that of Fíngen mac Áedo Duib (d. 618) of the Chaisil branch.
In his death obit in the Annals of The Four Masters this is said of him[8] "Aedh Beannan, of Eoghanacht Iar-Luachair,— Woe to the wealth of which he was king!
His shield when he would shake, his foes would be subdued; Though it were but on his back, it was shelter to West Munster" According to the saga Mór of Munster and the Violent Death of Cuanu mac Ailchine his daughter Mór Muman (d. 636) was married to Fingen and later married his successor Cathal mac Áedo (d. 627), thereby transferring the kingship to him.
