The Cenél nEógain reduced the size of the Aighiallan federation as the people of northern Airghialla came to be treated as sub-kingdoms of the Cenél nEógain. During a similar period the southern branches of the Airghialla came under the dominion of the southern Uí Néill kingdoms of Mide and Brega. In 9th century Airgialla proper, as a political entity, was practically confined to the modern counties Armagh, Monaghan, Fermanagh, and part of Louth, with the Uí Thuirtri kingdom in east Tyrone in process of being absorbed into the Cenél nEógain over-kingdom of Ailech.

(The Eastern area of Oirghilla: Orgialla Irish: ór, gold; giall, hostage, ie hostage of gold. Airgíallne, meaning "additional clientship". ) A people absorbed into the Cenel nEoghain .
The O'Neill's who match it is likely that at one time their ancestors adopted the surname O'Neill then centuries later thrived in Ireland after the 1600's till the 1800's . When the core of the O'Neill's of Ulster departed to Spain, Spanish Netherlands , Austria and the Caribbean. NRYQA 13 24 14 11

30 15 15 17 17 Note: This is just basic research on written historical legendary genealogy of the Irish and Y-DNA study. Nothing conclusive but it looks to be the reason why none of the current O'Neill's match the supposed Ui Neill modal. Futher research is needed. But i believe this to be the Y-DNA of people absorbed into the Cenel nEoghain clan.
