TURNBULL, TRIMBLE, TREMBLE, TRIMBEL, TRUMBLE, TRUMBULL, TURNBOW and any other reasonable spelling variations are welcome to join the project. While this is primarily a Ydna project, anyone with Trimble/Turnbull heritage is welcome to join. We are currently looking at ways to group both autosomal and Ydna results together. To participate meaningfully, testees will need to share their ancestry back to the earliest known TRIMBLE/etc., with a pedigree (excluding living persons) using the tree utility.
