Ok, basically he covers the material in other places, Clans and SNPs, also the research report "Calibrating with Historic Figues" covers essentially the same ground...Spencer is not the first researcher to develop this, Dr Richard Macgregor, in his Blogspot annual reports, around 2015 using dendrograms demonstrates a common nexus, however his data only inculuded Macgregor project participants ( of which a few McFarlands were included), BUT Spencer was the first to basically prove the existence of Siol Alpin demonstrating a clear founder effect at S744 ( FTDNA dates S744 at abt 400AD, this seems too early for any Kenneth typically dated to 700-800AD, but perhaps Fergus) MAC
