The proposed relationship of Harriet Tompkins as the mother of Roy Eugene Stockton and Benjamin Franklin Stockton is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 2nd cousin, once removed relationship between DB (a descendant of the Roy Eugene Stockton ancestral line) and KP (a descendant of the Benjamin Franklin Stockton ancestral line) with a shared segment of 114.08 cM across 6 HIR segments.

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