Welcome. Nimmo and any other reasonable spelling variations are welcome to join the project. Scotland appears to be the origin of this family in the United States. Only males have Y-chromosomes, so only male Nimmo. can participate. If you are female, you can have a male Nimmo. 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 Nimmo, in the form of a pedigree chart (excluding living persons).
