Project Background:
A surname of itself can often hide the real origin of a family. With religious changes and great movements of people, names can be changed to suit the circumstances families face. In Irish history this has been a come thread in regard to names and many people may find that by tracing the name the family now has, they hit brick walls, where the line ceases.

The name O'Brien has been around for nearly a thousand years, but from that name many other surnames have devolved. While some of these changes can be shown through the traditional paper traces, most have started in mystery.

Irish families often faced the hardships of famine and poverty and many children were often "adopted" out to allow for the survival of the group. Typically, if land was rented by Spinsters, then they might "adopt" a male child from another family, who would use their name as his.

Therefore DNA-testing gives us concrete evidence for identifying and separating family lines. Y-chromosome DNA testing is especially helpful because the male Y-chromosome is handed down, father to son, basically unchanged through the generations, except for rare mutations which, in themselves, can be helpful indicators of branching.

Accessibility to family DNA testing is doubtless the greatest technical advance in the history of genealogical research because -- at long, long last -- we have a tool to break down those brick walls!

So what are you waiting for?


Project Goals:
The main goals of the O'BRIEN Surname Project is:
1) To distinguish between O'BRIEN ancestral lines, worldwide. This covers any reasonable spelling variant.
2) To try and build links between all the families, despite the spelling variation, and see how this proud Irish name has changed and moved around the world.
3) To "cast the net widely"; By asking participants to allow there results to be made available to all other participants.
4) Also encourage participants and to join the Ysearch program.
5) To ask participants to upload their GEDCOM* so that links and research can be made.

If we all join in and follow the above goals, we may all be in for some surprises with regard to where our families come from and where we all connect.

* GEDCOM is a data file created by all Family Tree Software products, sharing your male direct-line ancestry either in the form of a pedigree or, preferably, as family group sheets, allows the maximum change of getting meaningful results.

DNA Test Results (Alleles) for Project Members

* Haplogroups in green have been confirmed by SNP testing. Haplogroups in red have been predicted by Family Tree DNA based on unambiguous results in the individual's personal page. This has been placed on this GAP page for your ease and convenience. Please note that for any predicted results we see no reason for ordering a SNP test to confirm the Haplogroup. if a – is in the HAPLO field then we feel that the comparative results are not clear and unambiguous and if the kit holder wants to know their SNP with 100% confidence they may consider ordering a SNP confirmation test.
