About us

To see all Ireland yDNA Project results, please set the number of results shown to 6,100 or higher.

The Ireland yDNA Project welcomes males who are doing or who have done a y-chromosome DNA test (yDNA) and who also have Irish ancestry on their own paternal line. This includes National Genographic Project (Geno 2.0) transfers. Please note that it is a yDNA Project only. Members need to have done or plan to order a yDNA test to be eligible for membership as we focus only on yDNA in this project.

Please use the "Join Projects" link, if you wish to join this project. You will need to send us a request to join and we hope you will take the opportunity to tell us about your paternal line and why you want to join. We them process your request.


Check that you are doing or have done a yDNA test and that you have Irish lineage on your own paternal line.


Don't worry if your surname is not listed, all men with Irish ancestry on their paternal line are welcome to join the project provided they do a yDNA test. [updated January 2015]
