Thanks so much, Sue, for your patience and explanation.  I have been in contact with another descendant of Martin Kincaid and I have mentioned to him about the DNA test but I have not heard back from him.  What I see out of this is that there appears to be more mutations (more or less random) within a ten to twelve generation period than I have understood to be (1 in 30 to 40 generations is what I have read).  And there are the fast moving markers and the slow moving markers.  It would be interesting to have my brothers, my two Kincaide nephews and my older brother's Kincaide grandsons and my Dad tested to see what the result would be.  From the previous discussions I would bet money that there would be mutations within the span of 4 generations within a population of 8 male Kincaides, myself included.  Since this process is only about ten years old there is much more to be done toward refining the results and understanding mutations. Sincerely Norman Kincaide
