As of July 2013 we have results for 40 families.



Surname yDNA testing is the newest tool available to genealogists!

  • Surname yDNA tests allow genealogists to verify their father's father's...father's paternal ancestry. As this test traces a males paternal line, a male must be tested.
  • Surname yDNA information can be very powerful when combined with traditional paper trails.
  • A 37 or 67  marker yDNA test is recommended for this project, (Or a 46 marker test if tested at Ancestry/SMGF)


The Corrigan yDNA Project is open to all Corrigan, Carrigan, Currigan males, of all spelling variations, and from all locations.

As Kerrigan can often be found interchangeably with Corrigan and Carrigan in records of the 18th, 19th and 20th century,  it is also included.

Cargen, Cargon, Carrigan, Carrocan, Carrogan, Carroghan, Carrucan, Corgan, Corragan, Corregan, Corrigan, Corrigane, Courigan, Currie, Currigan, Curry, Kerrigan, Kirgen, O'Corrigain
(If your surname is not included please contact the Project Administrator.)


The Corrigan yDNA Project Family Project was started to:

  1. Help researchers from common or related families work together to find their shared heritage.
  2. Identify how the participant's families are connected, both genetically and through paper trails.
  3. Identify and confirm genetic Lineages of ancestral families.
  4. Ultimately catalog pedigrees and genetic connections of all of the known project families.


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

Demolishing those Brickwalls All family genealogists will hit the proverbial 'brickwall' sooner or later. Many researchers suspect other lines, with the same or similar surnames, could be connected to their tree. Unfortunately there is often no documentary evidence available to prove it. This project will hopefully provide an opportunity to remove some of these 'brickwalls'.

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

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

The Ladies Please don't forget how important the ladies are when it comes to organising things. So whilst it's the Corrigan males that supply the Y-DNA it could very well be the ladies that provide the organisational 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.
