I would appreciate a few opinions on my Y Chromosome matches
I took the 12 marker Y Chromosome test a couple of years ago mainly to get a predicted haplogroup. I found I had made an exact 12-marker match with two other members of my surname project (DAVIS). As Davis is a very common surname and I have 300+ other 12 marker matches with people with other surnames I did not read too much into this.
I ordered the family finder test earlier this year and that re-ignited my interest in the earlier Y Chromosome results and I decided to upgrade. At 25 markers I had a single exact match. This was to someone with the surname SMETTERS. At this point I wondered if this match was from before the genealogical paper timeframe or an indicator of a possible false paternity event. I also had 14 genetic distance of 1 matches at 25 markers and 10 of these with individuals with surname variants of SMETTERS. With so many SMETTERS matches I was then concerned that the false paternity event may have been in my direct line.
However the exact SMETTERS match at 25 and the 11 other genetic distance 1 SMETTERS at 25 have all tested at 37 or higher markers as well and when I compare them to my 37 marker results none of them match me at all at 37 markers even as far out as a genetic distance of 4.
So based on the 37 marker results I am leaning towards it being more probable that my relationship to the SMETTERS is from before the period when surnames formed and less likely to indicate a false paternity event in my Davis line.
Does this conclusion sound reasonable in terms of its probability?
