Old Augusta Hays
Public data, extracted 18 June 2014 from the FTDNA Hayes YDNA project, were used to see how closely the YDNA hapotype's of the kits in the Hayes YDNA project. A proprietary program, yALL2, was used to make these comparisons, using mutation rate weighting to account for differences in the rate of mutation for different markers. The results of this analysis shows that the Hayes YDNA project at FTDNA contains 10 kits testing at 37+ shared a relatively recent common ancestor. 
The following matrix shows the "dis-similarity" between haplotypes for each and every kit in this group of ten kits. Values of "0.0%" indicate that the haplotypes for two kits are exactly the same. Increasing values of dissimilarity indicate that kits are less and less similar to each other. These data show a maximum dissimilarity of about 4%. Values like this are indicative of a relatively recent common ancestor.
