The proposed relationship of Margaret A "Maggie" Mixer as the mother of
Margaret L Gibson and NG is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a 2nd cousin, once removed relationship between TH (a descendant of the Margaret L Gibson ancestral line) and JG2 (a descendant of the NG ancestral line) with 92.10 cM of shared DNA across 4 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
