The proposed relationship of Pauline Louise Mott as the mother of Helen Faye Hines and SH is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 1st cousin, once removed relationship between RLB (a descendant of the Helen Faye Hines ancestral line) and MD (a descendant of the SH ancestral line) with a shared segment of 641.21 cM across 24 HIR segments.

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