Using modern genetics to unite families researching their Ryan ancestors
FTDNA recently introduced a new feature that Project Administrators have been asking for for quite some time. It is called the Group Time Tree and (like Alex Williamson's Big Tree), this one has surnames of all Big-Y-tested individuals, together with their surname, their MDKA (Most Distant Known Ancestor), and the specific downstream branch of the Tree of Mankind on which they sit. But in addition, it includes the most advanced TMRCA estimates (Time to Most Recent Common Ancestor) for each branch in the Tre
This new feature incorporates the vastly improved age estimates for each of the various branches within the "genetic family tree" and this allows us to see (with a lot greater precision) how closely any two groups within the project are related to each other. And indeed it can even show how all the groups in the project are related to each other - see the diagram here , which shows (not surprisingly) that everyone within the project shares a common ancestor who passed down the SNP marker M168 and lived a
