Corrigan & variants yDNA Project- Background



Cargen, Cargon, Carrigan, Carrocan, Carrogan, Carroghan, Carrucan, Corgan, Corragan, Corregan, Corrigan, Corrigane, Courigan, Currie, Currigan, Curry, Kerrigan, Kirgen, O'Corrigain


We have a new website to show results from all testing companies, FTDNA,, SMGF.  Please visit  
Corrigan DNA Project  for the complete results.

We are seeking male Corrigan, Carrigan, Currigan and variants worldwide. All variant spellings are accepted. (Kerrigan is of a seperate origin, but will be included as it is often used interchangeably with Corrigan and Carrigan)
We are looking to determine whether there are multiple O'Corragain lines and where they are from.
Which line does your family connect with?
Y-chromosome DNA is passed down from father to son for many generations, with very little mutation. The mutations themselves can help indicate branching off of family lines. Along with traditional genealogy, Y DNA testing within a surname project can give us firm evidence for identifying and separating family lines.

Donations for specific research areas If any member wants toencourage people with known roots in their ancestors region to order akit please make a donation to our General Fund.

Demolishing those Brickwalls All family genealogists will hit theproverbial 'brickwall' sooner or later. Many researchers suspect otherlines, with the same or similar surnames, could be connected to theirtree. Unfortunately there is often no documentary evidence available toprove it. This project will hopefully provide an opportunity to removesome of these 'brickwalls'.

Joining of existing family trees If you suspect you arerelated to another family group then why not use Y-DNA testing to proveit. All it takes is 2 tests, one Corrigan male from each line, to findout if you have a Y-DNA match. You may prove connections not only tothe obvious groups but to others from around the world.

Spreading the cost If you are concerned about the costthen please consider that you can spread it between your familygroup. For example, if you have a proven family tree then only onedirect descendant male needs to submit a sample. So every member withina group could share the costs. Talk to us nicely and we may make asmall donation to your test.

The Ladies Please don't forget how important the ladies are whenit comes to organising things. So whilst it's the Corrigan males thatsupply the Y-DNA it could very well be the ladies that provide theorganisational skills necessary to get those men to do the test.

O'Corragáin Surname Origins; O'Corragáin (in Gaelic), the sept belongs primarily to Fermanagh being of the same stock as the Maguires.
Corrigans - the prefix O is seldom used - are still in that part of Ulster, but the name to-day is very scattered, being found in most counties, except in Munster. This was already the case in the sixteenth century when it appears in localities as far apart as Offaly, Roscommon, Meath and Monaghan. In the 1659 census Corrigan and O'Corrigan are among the more numerous Irish names in Offaly, Longford, and Fermanagh. The place called Ballycorrigan near Nenagh in Tipperary, indicates that a leading family of Corrigan was seated there not later than the middle of the seventeenth century.
The majority of the references to O'Corrigáin/Corrigan in the Four Masters are to abbots and other ecclesiastics in Co. Fermanagh.

"(0) Corrigan O Corragdin. Akin to the Maguires, originally, of
Fermanagh, now scattered. Ballycorrigan, for example, is in Co. Tipperary,
though possibly this place name may not be derived from the surname. As
Currigan and Courigan, it is now found in east Connacht, and as Carrocan in
Co. Clare." p. 60

Kerrigan is aslo being looked at as Kerrigan has often been confused with Carrigan and Corrigan, especially in the new worlds the Irish migrated to, USA, Canada, Australia, New Zeealand etc..   Corrigan occured in the Westport area of Co. Mayo as a synonym of Kerrigan; and Carrigan is interchangeable with Kerrigan in Co. Fermanagh. Carrigan is etymologically a variant of Corrigan not of Kerrigan.

This project is administered by myself, Frances James, as a volunteer. Genealogy is my hobby.
I recieve no payment, I do not work for, nor am I associated with Family Tree DNA in anyway, apart from being a paying customer, like any other participant of a project.
