The proposed relationship of Margaret T Potts as the mother of
Benjamin Franklin Norris and
David Jasper Norris is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a distant cousin relationship between MN (a descendant of the David Jasper Norris ancestral line) and TN (a descendant of the Benjamin Franklin Norris ancestral line) with 66.43 cM of shared DNA across 2 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
