The proposed relationship of Molsey Gibbs as the mother of Susan Simmons, Lula Simmons and Lincoln Albert Simmons is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 3rd cousin, once removed relationship between JL (a descendant of the Susan Simmons ancestral line) and CC (a descendant of the Lula Simmons ancestral line) with a shared segment of 38.43 cM across 2 HIR segments.

It also confirms a 3rd cousin, once removed relationship between LT (a descendant of the Lincoln Albert Simmons ancestral line) and JL (a descendant of the Susan Simmons ancestral line) with a shared segment of 30.22 cM across 2 HIR segments.

These matches are consistent with their placement within these shared ancestral branches.
