The proposed relationship of Mary F Wilson as the mother of John F Sayers and CS is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 2nd cousin, once removed relationship between PR (a descendant of the CS ancestral line) and ANZ (a descendant of the John F Sayers ancestral line) with a shared segment of 131.94 cM across 6 HIR segments.

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