The proposed relationship of Kenneth Dean Jordan as the father of PJ and DWJ is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a Niece / Nephew relationship between PJ (a descendant of the PJ ancestral line) and GJ (a descendant of the DWJ ancestral line), with a shared segment of 1630.32 cM across 43 HIR segments. This match is consistent with their placement within these shared ancestral branches.
