HANSON, HANSEN, HENSON, HINSON, HANSSON, HANSAN, HANZON, HOUNSON, HANSSEN, HENTZEN and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male HANSON (or variant) can participate. If you are female, you can have a male HANSON (or variant) 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 HANSON (or variant) in the form of a pedigree (excluding living persons).
NB if you have one of the project surnames and can also trace your paternal ancestry back to a location in Scandinavia, please consider joining both this project and the Scandinavian Y-DNA project. See www.ftdna.com/public/scandinavianydna/ for more details.
