The O'Brien Surname Project

Description:

O'BRIEN, O'BRIAN, O'BRYAN, 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
