A gd of 13 or 15 on a comparison of 67 markers is quite large. According to FTDNA's guidelines for interpreting 67-marker reuslts (...

A gd of 1 on a 37 marker comparison is fully consistent with sharing a common grandparent.

Yes, a genetic distance of 3 on a comparison of 37 markers is consistent with, and supportive of (but not proof of), 2 men sharing a common ancestor in that time frame.

It is the norm for someone who is R-M269 to have tons of matches based on a genetic distance of 0 or 1 at 25 markers. I myself have 176 of those matches, only 1 of which (at a genetic distance of 1)...

I think it is highly likely that the Wilson matches share a common ancestor within the genealogical time frame. The non-Wilson match could be an NPE or the result of convergent mutation (where people...

I agree that the McManus connection sounds the most promising because you have a very close 67 match as well as some autosomal matches. Re the Upchurch and Oakley matches - There are many possible...

It's very common and doesn't really suggest much of anything. It could be explained by convergent mutations, back mutations, or higher than expected rate of mutation. None of which are unusual. You...

Yes. A change from 12 to 9 on DYS388 could have happened through a single mutation in one generation, so if you match someone reasonably closely based on the other marker values, you might well be...

Dr. B - Could you please list your values for the first 12 markers? That way we can see what is causing your failure to match - eg lots of off-modal values or a single value that is extremely...

All men with the same terminal SNP should have very similar STR signatures. I don't think there is any meaning to particular STR values beyond that, however.
