The proposed relationship of Bert Lee Estes as the father of LAE and DRE is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a great aunt / uncle relationship between BW (a descendant of the DRE ancestral line) and JW (a descendant of the LAE ancestral line) with a shared segment of 821.05 cM across 35 HIR segments.

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