The proposed relationship of Lelah May West as the mother of Harold Eugene Bost and CEB is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between DS (a descendant of the CEB ancestral line) and FL (a descendant of the Harold Eugene Bost ancestral line) with a shared segment of 156.36 cM .

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