As of 4-5-19 these were all of the subjects that I had access to their data to make our Johnston Phylogenetic Tree. When this "long" JPT is compared to the "short" JPT it is interesting to see how well the dates match up. For the Pater Familias of Clan Johnston/e, John Johnstoun, there is a difference of only 45 years over a time period of almost 900 years. For the 2 more recent comparison groups, they match perfectly. See the "short" JPT image posted right after this one.
