Both my 2nd cousin and the 3rd person are related to me through my father's line. But, your comment made me go back and look closer. My 2nd cousin and I are related on my father's side (our MRCAs are from my paternal grandfather's line). The 3rd person is a match I have here on Ancestry and our trees indicate our MRCAs are also on my father's side (our MRCAs are from my paternal grandmother's line). Obviously, my father could not have passed down to me at the same location on Ch 4 two different segments, one that matches one of these people and one that matches the other. This leaves me to conclude that the 3rd person and I are somehow related through my mother's line as well as my father's line, thus giving us 2 sets of common ancestors, one on my father's side already identified in our trees but not associated with this segment, and one on my mother's side, yet unidentified, that must be associated with this segment. That is the only way this would work. The segments begin at the exact same point, 61,566. My 2nd cousin's segment ends at 7,546,875 and the 3rd person's segment ends at 8,134,463. Thanks for your reply.
