There are way too many holes in the GSMD "Women of the Mayflower" endeavor, and I do not accept that it is the "final nail in the coffin" for Constance/Constant (Snow) Doane. Great idea, but perhaps poorly executed.
The mtDNA ‘study’ appeared in the above-cited Mayflower Quarterly basically as a human-interest blurb, as well it should have. I have not located a more detailed explanation with research parameters, appropriate citations or evidence (such as the proven descendancy of each of Constance Hopkin’s daughters’ descendants), or any of the like required of any substantial genealogical finding.
WoM found and tested two descendants of “the questionable daughter Constance” (Snow) Doane, of Constance Hopkins and Nicholas Snow. The author wrote, “the [paper] research of the lines was admittedly sketchy….” What?!!
Then, da-dum, the mtDNA of the descendants of Daniel Doane’s daughters (possibly from Constance Snow) Ruth (Doane) Mayo and Constance (Doane) Shaw, did not match their alleged (some degree) great grandaunts’ mtDNA (Sarah, Ruth, and Mary Snow), nor did they (descendants of Ruth (Doane) Mayo and Constance (Doane) Shaw) match each other “well.”
Good grief. My forte is not DNA, but, boy, something smells off here.
