Corum, Coram, Corham, Corrin, and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male CORUM/etc. can participate. If you are female, you can have a male CORUM/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 CORUM/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 http://spaces.msn.com/members/patisspace/
Thank you and good hunting,
Pat
