CLAN DNA PROJECTS

 

Many Irish clans now have yDNA surname projects. These are based on the inheritance of the yDNA chromosome down through the paternal line. This kind of project is ideally suited to families bearing Irish patronymic surnames as the yDNA results generally reflect the surname.

The goals of Irish yDNA surname projects usually include the primary one of finding of relatives in Ireland. The goals sometimes include the desire to verify paternal ancestry and the identification of place of origin of the family. A history of the clan and its various branches can also be part of the goals of Irish Surname projects.

It has been the case for years that "Irish" yDNA Surname Projects have attracted people from many countries but they held little interest for the Irish who were still resident in Ireland. The argument has been that Irish who live in Ireland “know where they come from” and don’t need to do DNA tests.

However, Irish yDNA Surname Projects really need Irish-based participants to get involved in yDNA testing, for several reasons:

Irish-based families may wish to connect with relatives, who may have emigrated in times past, where there is no paper trail or living memory to help with making these connections. How many people in Ireland can say “most of my family emigrated in the Famine and we have no idea where they went or who their descendants are”. Or “we have no contact with branches of our family who left Ireland a long time ago”. Must this be the case? DNA can open doors for the Irish who have lost track of relatives.

Also, if more Irish men were involved in yDNA Surname Projects it would help the Irish diaspora who need yDNA results of Irish-based participants, to serve as "benchmarks" in their genealogical research. It is an exciting way to bridge the gap between the sometimes sad lonely emigration of the past and the modern world of global communications.

There are many commercial DNA companies which do yDNA testing. Those clans which are members of the Clans of Ireland, and have DNA projects going on, are listed below. If you click on a surname project link it will take you to the information about that particular project and give details of what is involved.
We encourage interested Irish clan members to look for their own surname DNA Project but if none exists for their surname, note that the Ireland yDNA Project caters for all Irish surnames. The Ireland yDNA Project website is at:

Please note that the science of DNA is still evolving and that membership of an Irish Clan is based on one's inherited and chosen identity and not on bloodline descent alone.
