Hi Peter: Still a belated sorry for delayed reply. My wife passed away on the day you posted: Febr. 28.... Yes, precision takes time and treasure. My grandson enrolled in the Genome-2 Project, got a unique result, not ISOGG recognised or designated, so I became intrigued, had my Y-dna done at FTDNA, first Y-111, then the big-Y at approx. $700 total, which gave the results that led ISOGG to assign the subclade R-A8043. For Burke's to check whether they match the Burke listed in the phylogenetic table may possible require only testing for one subclade - go talk to your group administrator. Whether FTDNA wil cooperate, that's for them to decide. They have not responded to changing my designation from M269 to R-A8043, exceot on my personal profile.
