I wonder if anyone has any examples they can share with us." I was behind in my reading of this group, and just came across this. I do have a couple of examples from my own chromosome mapping. I match two 4th cousins on chromosome 13, in amounts of 10.4 and 10.8 cM (these are both from Ftdna). Each of us descends from a different child of the common ancestral couple. Another person matching at the same spot lists one of the surnames of the ancestral couple in her profile, but has not responded to queries. In another situation, on chromosome 5, I match four 4th cousins once removed. (They would have been my late father's 4th cousins.) All of them descend from the same son of the ancestral couple. Two of them are 2nd cousins to each other, but other than that, their descent is from different children of that son. I descend from the ancestral couple in two different ways (from two daughters). The matching amounts are 22.4, 5.9, 8.5, and 8.1 cM. These are all from Ftdna also. I realize that these are fairly small numbers, but it's near a crossover event for me. I also match four of my late father's 1st cousins at the same place, and their matching segments with those 4th cousins (at the same spot) are longer - in the range of 12 to 28 cM. Let me know if you have any questions. Karen
