The proposed relationship of Mary LEE as the mother of
Ann LAUNDON and
WIlliam Laundon is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a 3rd cousin, once removed relationship between Joan Patricia ROBERTS (a descendant of the Ann LAUNDON ancestral line) and NC (a descendant of the WIlliam Laundon ancestral line) with 28.67 cM of shared DNA across 1 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
