The proposed relationship of Emilie Pahlow as the mother of Walter Koepke and Arthur Koepke is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between MD (a descendant of the Arthur Koepke ancestral line) and CR (a descendant of the Walter Koepke ancestral line) with a shared segment of 71.88 cM across 3 HIR segments.

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