The proposed relationship of Martha Hamilton as the mother of
William Wallace Perry and
Palmer Perry is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a distant cousin relationship between MS (a descendant of the Palmer Perry ancestral line) and SRB (a descendant of the William Wallace Perry ancestral line) with 34.89 cM of shared DNA across 2 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
