MANN, MAN, MAHN, MAND, McMANN, McMAN, de MAN, and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male MANN/etc. can participate. If you are female, you can have a male MANN/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 MANN/etc., in the form of a pedigree (excluding living persons).
