Hi Cathy,
I just did a comparison between your brother, and Tom & myself. Below is a comparison between we three.. out of 46 markers, I match your brother in only 34, Tom matches your brother in 33: so its several generations back before your brother & I share a common ancestor,,,,, something in the range of 40 or 50 generations or more, just off by one sequence and it's 7 or 8 generations before you have a common ancestory--the DNA within the Y chromosome just doesn't mutate very often..... So I guess the Thomson-being MacTavish-thing would be true---if you go back 50 generations or so!!!!! Lets see, 50 generations back would put us about the time the neolithic hunter-gatherers were settling Scotland, so yea, that's when we had a common ancestor. Seriously, I think this is rather important. It proves the lie that Thompsons' are really MacTavishes...genetically, it's not possible.....
Below is my DNA, Tom's difference to me is listed in ( ), Cathy's brother difference to me in { }
