If your 3 ¡°matches¡± are STR matches it is because STR matches are fickle due to parallel, back, and rapid mutations.? STR matches always include some degree of uncertainty.
When I took the Y-37 test in 2016 I had no matches at 37 STR or above. Upgraded to 111 markers, no joy. In 2019 a remote cousin appeared at 111 (6 steps) so we took the Big Y 700 test. We match on that test with 6 non-matching variants. The test established our Haplogroup R-FT201177, a little German enclave, in mostly British R-Y8604 under R-S5245.? My guess is that there are at least a 10 Big Y tests in R-Y8604 but I don't match any of them.?
However, I do match 3 guys in other subclades under R-S5245. Why them? Did they take the original Big Y and so have fewer non matching variants to count for the map algorithm??
