The proposed relationship of Johann Gottfried Parlow as the father of
Bertha Emilie Alwina Parlow and
Frank Parlow is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a 3rd cousin, once removed relationship between WF (a descendant of the Frank Parlow ancestral line) and JR (a descendant of the Bertha Emilie Alwina Parlow ancestral line) with 77.57 cM of shared DNA across 3 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
