RUSHTON, RUSTON, RUSHTEN, RUSHETON, RUSTEN, RUSTIN, and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male RUSHTON/etc. can participate. If you are female, you can have a male RUSHTON/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 RUSHTON/etc., as a pedigree (excluding living persons).
