Just in case a cladogram might shed any light on yesterday's discussion, I prepared this one including all in both families (and Mr. Bell) who had tested FTDNA's contiguous 37 markers -By definition, this excludes #31, #59 and #84. Too bad.
One interesting observation: Mr. Bell and David, #161, are a genetic distance of two separated by a median vector. According to Forensic Genealogy by Colleen Fitzpatrick, PhD, "median vectors can represent future participants in the study or ancestors whose haplotypes have become extinct."
