We have a new website to show results from all testing companies;
Corrigan DNA Project




We are seeking male Corrigan’s worldwide. All variant spellings are accepted.
We are looking to determine whether there are multiple Corrigan 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.


The test is a simple cheek swab, a kit with 3 special scrapers and lids. The kit is mailed to you by FamilytreeDNA. You rub the inside of your cheek with each scraper and place in a provided envelope to return by mail.
(As we are looking at sections of the yDNA that are the same for many generations, the same from father to sons, there is no idenitfying information useful for forensic or insurance cases.)


For genealogical purposes a 37 marker test or more is recommended.
You may wish to start with a 12 or 25 marker test, then upgrade as you wish.

FTDNA have a section on;
How many markers are enough

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.

Some known variants of the surname O'Corragáin are;
Carrigan, Carrogan, Corragan, Corrigan.
Currigan and Courigan in East Connacht,
Carrocan in Co Clare.

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.
