BISHOP, BISCHOF, BISCHOFF, BISSCHOFF, and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male BISHOP (or variants) can participate. If you are female, you can have a male BISHOP (or variants) 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 BISHOP (or variants), in the form of a pedigree (excluding living persons).
