Sovereigns of Ireland (the High Kings)


The sons of Niall of the Nine Hostages included Eoghan and Conall Gulban, the progenitors of the Cenél Eóghain and Cenél Conaill dynasties of northwest Ulster. Referred to in Irish history as chief dynasties of the northern Uí Neill, the Cenél Eóghain and Cenél Conaill shared a common heritage as early sovereigns (cerimonial High Kings) of Ireland along with their cousins in the middle kingdoms of Midhe and Brega, i.e. the southern Uí Neill.

There are many notable northern Uí Neill clans which included the various families of O'Neill, O'Donnell, MacLoughlin, O'Donnelly, O'Doherty, O'Cannon, O'Muldory, O'Kane, O'Gallaghers, O'Gormley, O’Flaherty or O’Laverty, O'Hamill, O'Lunney, O'Carolan of Clan Diarmada, among many others.
