NORRIS, NORRISS, NORRASS, NORAAS, NOURSE, NURSE, and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male NORRIS/etc. can participate. If you are female, you can have a male NORRIS/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 NORRIS/etc., either in the form of a pedigree chart or, preferable, family group sheets (excluding or anonymizing living persons).
