The proposed relationship of Homer Dale Day as the father of PMD and CMD is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a distant cousin relationship between AD (a descendant of the PMD ancestral line) and LMC (a descendant of the CMD ancestral line) with 339.18 cM of shared DNA across 12 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
