REASON, RAYSON, REASONS, REASIN, REESON, RESON, RASIN, RESIN, REZIN, RAZAN, RYSON, RYESON, RYASAN, REISIN, REISING, RAISON, RISON, and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male REASON/etc. can participate. If you are female, you can have a male REASON/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 REASON/etc., as a pedigree (excluding living persons).
