By re-processing and analysing Y-genome and Whole Genome test results, between 2010 and 2020, this Project discovered dozens of new A-series SNPs.

The goal set by William Hartley was to discover new SNPs and Branches that lie between I1-M253 and the DF29 Branch. The main Branches are I1-M253 > CTS12768/M1182, and > Z17954

The Project STR Results Table shows the new SNPs and Branches discovered, so far, and forms a I1-M253 > Z17954 Tree

Early Discoveries of SNPs

All we had to go by in 2004 to 2012 were a handful of useful SNPs that we placed into a very small I1-M253 Tree, namely M253, DF29, Z131 ...

”The goal of this Project has been achieved !! “

Where we once knew very little about that part of the I1-M253 Tree, we now know a great deal.

Owing to the success of the I1-Z17954 [xDF29] Project, we now have dozens of new A-series SNPs that populate the Z17954 Branches.

However, the focus now is on discovering SNPs that lie in a genealogical time-frame, ie, the past 500 years. And some Z17954 Branch groups have already had success ...
