The proposed relationship of Clinton Earl 'Billy' Ratliff as the father of EAR and NLR is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a great aunt / uncle relationship between KI (a descendant of the EAR ancestral line) and BH (a descendant of the NLR ancestral line) with a shared segment of 1092.51 cM across 37 HIR segments.

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