The proposed relationship of Lucinda Conway as the mother of Sarah Frances Gentry and FMG is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 3rd cousin, once removed relationship between DSM (a descendant of the FMG ancestral line) and MLA (a descendant of the Sarah Frances Gentry ancestral line) with a shared segment of 160.70 cM across 8 HIR segments.

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