The Turnbull-Trimble-Tru Surname Project
TURNBULL, TRIMBLE, TREMBLE, TRIMBEL, TRUMBLE, TRUMBULL, and any other reasonable spelling variations are welcome to join the project. Only males have Y-chromosomes, so only male TRIMBLE/etc. can participate. If you are female, you can have a male TRIMBLE/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 TRIMBLE/etc., with a pedigree (excluding living persons).
