POTTER, POTTERS, POETER, POTIER, POITIER, POTHIER, DE POTTER, and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male POTTER/etc. can participate. If you are female, you can have a male POTTER/etc. relative submit a sample for your line. To participate meaningfully, testees may wish to share their direct male line ancestry back to the earliest known POTTER/etc., as a pedigree chart (excluding living persons). 18 May 2018 - See NEWS section for important announcement
