The proposed relationship of Rachel Knight Rizor as the mother of Sadie Lenora Jones, Mary Catherine Jones and Edgar Owen Jones is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between KLF (a descendant of the Sadie Lenora Jones ancestral line) and CL (a descendant of the Mary Catherine Jones ancestral line) with a shared segment of 63.70 cM across 4 HIR segments.

It also confirms a 3rd cousin, once removed relationship between KLF (a descendant of the Sadie Lenora Jones ancestral line) and SB (a descendant of the Edgar Owen Jones ancestral line) with a shared segment of 69.89 cM across 3 HIR segments.

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