SWANSON, SWENSEN, SWANSSON, SWENSON, SWENSSON, SVENSON, SVENDSON, SVENDSEN, SVENSSON, SUENSON, SWENDSEN, SWAINSON, SWAINSTON, SWAYNSON, SWYNSEN, ZWENDSEN, and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male SWANSON/etc. can participate. If you are female, you can have a male SWANSON/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 SWANSON/etc., as a pedigree (excluding living persons).
