O'BRIEN, O'BRIAN, O'BRYAN, O'BRIANT, O'BRYANT, O'BRYEN, OBRIEN, OBREGON, BRIAN, BRIANT, BRIEN, BRYAN, BRYEN, BRYANT and any other reasonable spelling variations, including aliases, such as PRINS and UBRY or UBRI, are welcome to join the project. The main results are comparing Y-chromosomes, these are handed down through the Male line only. For female Clan members, it would be good to find a male relation, of the same surname, and have them tested. To participate meaningfully, the person sampled will need to share their direct male line ancestry back to the earliest known O'BRIEN/etc., either in the form of a pedigree chart or, preferable, family group sheets (excluding living persons). For further information, please see the web page here at FTDNA. Thank you and good hunting, Dennis O'Brien
DNA and Family History
The project is a tool-kit that assists people in finding out which groups they belong to; verification of relationship; or just trying to find additional information, to hopefully piece together the chaotic history that makes Ireland so interesting and fascinating,yet frustrating; when putting the fabric of your family together.
While it may be nice to know your distantly related or a descendant from a particular Icon of Irish history, surely its the excitement of being able to link with some distant relative in the Ireland, US, Australia, Canada, South Africa, South America or any other place on earth; or to be able to place yourself within a particular group or region that is the true benefit of the DNA project
An O'Brien (or derivatives) 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 common 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 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 war, famine and poverty and many children were often "adopted" out to allow for the survival of the group. One example was when 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 that, by themselves, can be helpful indicators of branching.
It is important to also check the options regarding test for specific SNP’s, these results can sometimes some clearer connections.
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?
Dál gCais (L226) and Niall Noígíallach(M22) within the O’Brien’s Surname Group
You may be aware that while a lot of O’Brien’s or derived names are generally from Ireland, the fact is that Ireland itself is made up of many sub-groups and Clans that may have similar surnames but they are not related to each other.
As surnames are a recent invention, no more that 800 years or so, a lot of individuals or groups adopted names that may have political,cultural or other reasons. Thus it is a fact that many within this Project find themselves displaying results that raise questions about their heritage.
As far I am concerned I welcome all with an associate name and do not judge about how that name came about.
However there are a large group of members who are identified with the “Dál gCais” group represented by the SNP of L226. This SNP has shown great restraint and it is apparent that it only belongs to a particular group of Irish people. It also has a direct relationship with the O’Brien’s and related Clans associate with Brian Boru and his extended family. (We know this because an existing member of that family is also L226.)
