Corrigan & variants

About us

We have 2 main yDNA groups among the Corrigan men tested,  which can tell us something about the origins of the Corrigan clan.

R1b - L21> L513> L69 -  the Airghialla group;  Men in this group share very close yDNA results with Maguires, McMahons and other surnames associated with the ancient territory of Airghialla/Oriel, part of the Ulster kingdom,  founded by the Three Collas in 4th century, confirming the ancient connection between the O'Corrigans and Maguires.
We have 20 men in this group.

(O'Corragáin (in Gaelic), the sept belongs primarily to Fermanagh being of the same stock as the Maguires.)

See Kingdom of Airghialla, at Irelands History in maps;

Colla-da-Chrioch - The first king of Arghialla would be Colla-da-Chrioch (aka Colla Fochríth).
From Colla-da-Chrioch are claimed to descend some of these noble families of Ulster and elsewhere - Boylan, Brassil, Cahil, Callaghan, Carbery, Carey, Carroll, Cassidy, Conan, O'Connor, Corrigan, Cosgrave, Devine, O'Donnell, Donnelly, Duffy, Dwyer, Fogarty, Garvey, Gavin, Hanlon, Hart, Higgins, Hollgan, Kelly, Kennedy, Keogh, Lane, Larkin, Leahy, Lynch, MacCabe, MacDaniel, MacKenna, MacMahan, MacManus, Madigan, Madden, Maguire, Malone, Mitchell, Mooney, Muldoon, Norton, Orr, Traynor, Tully, etc.

R1b - L21> M222 - associated with many individuals whose roots lie in the counties of Northwest Ireland, Ulster and Lowland Scotland.
We have 11 men in this group. 
Our "R1b - Group 01" are from County Mayo, one of the hotspots for M222.

Early attempts at linking haplogroup and Irish surname were over-hasty in their conclusions. The Y-DNA haplogroup R1b-M222 was initially thought to mark the descendants of Niall of the Nine Hostages. It is carried by nearly 20% of the men in Donegal today. In early historic times this was the territory of the northern Uí Néill, presumed descendants of the fabled 5th-century warlord.R1b-M222 is particularly common among those with some purported Uí Néill surnames such as Gallagher, Boyle, Doherty and O’Donnell, though not most of the O'Neills themselves. It also appears among the Connachta, supposed descendants of the brothers of Niall.3However wider testing has revealed that Donegal is not the hotspot forR1b-M222. The highest concentrations have been found in Belfast, in North-Eastern Ireland (44%), and Mayo in Western Ireland (43%). The figure for the latter may be unreliable, as there were only 16 men sampled from Mayo, but these new figures do suggest that the distribution map drawn from early testing needs to be revised. Outside Ireland there are roughly 10% of men carrying M222in Northern England (Yorkshire), Western Scotland (Skye) and North-Eastern Scotland (Moray).4 Though migration from Ireland could account for some of the British M222,the pattern is unexpected for radiation from Ireland. So M222 is more likely to be a La Tène marker, spread from Northern Britain into Northern Ireland around 200 BC. If so it would be present among the people of north-western Ireland centuries before the Uí Néill came on the scene - if they actually did. Brian Lacey has sifted the political propaganda from the history. He shows that the Cenél Conaill (Cannon, Boyle,Doherty, Gallagher, McMenamin, O’Donnell) and Cenél nEógain (Devlin,Donnelly, Gormley, McLoughlin, O’Kane, Quinn) peoples claiming to be Northern Uí Néill were probably locals who had adopted that designation to link themselves with the incoming elite.
