The proposed relationship of Venora Belle Watson as the mother of
Margaret Katherine "marge" Overbey and JWO is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a half 1st cousin relationship between KH (a descendant of the JWO ancestral line) and TDC (a descendant of the Margaret Katherine "marge" Overbey ancestral line) with 979.60 cM of shared DNA across 28 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
