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 a shared segment of 66.43 cM across 2 HIR segments.

This match is consistent with their placement within these shared ancestral branches.
