By testing another Kennedy from my locale I have now determined that my most terminal SNP is FGC5864 as this is the only one of my NGS SNPs that the other Kennedy is ancestral for. I have added this mini-branch into the tree of names. Its probably a bit obscure for the skeleton tree but I did add in FGC12948 as this spans multiple surnames and is of broader significance. I hope to be able to estimate the age of the FGC5864 branch later in the summer after some further testing. Iain http://www.kennedydna.com/M222.pdf http://www.kennedydna.com/M222_tree.png
