Jim, The matches range between 6.1 and 9.7 cM with anywhere from about 700 to 1000 SNPs. Even if half of these matches were to my dad's lines and half to my mother's, that still seems like a lot of "cousin matches" (at least 25) in that one small location. It may be worth checking on the few larger ones but I suppose many of them are from the atDNA soup. This is all fascinating. Thanks for your input.
