All HENDRY/HENDRIE males are welcome to join the project, but as only males have Y-chromosomes, only male HENDRY/HENDRIE can participate. If you are female, you can have a male HENDRY/HENDRIE 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 HENDRY/HENDRIE, as a pedigree (excluding living persons).
