Fergus mac Fogartaig
Fergus mac Fogartaig was King of South Brega of the Uí Chernaig sept of Lagore of the Síl nÁedo Sláine branch of the southern Ui Neill. He was the son of the high king Fogartach mac Néill. He ruled from 738 to 751.
The annals do not mention any events regarding him other than his death obit. His death obit, though, in the Annals of Ulster has significance as the first time the title King of Southern Brega is used.
His sons included Máel Dúin mac Fergusa and Cernach mac Fergusa, both called Kings of Loch Gabor as well as Ailill mac Fergusa, styled King of South Brega.
