The O'Brien Surname Project
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. Only males have Y-chromosomes, so only male O'BRIEN/etc. can participate. If you are female, you can have a male O'BRIEN/etc. relative submit a sample for your line. To participate meaningfully, testees 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 and the one at my genealogy web site:http://www.obrienclan.com/DNA.htmThank you and good hunting,Mike
