Walter Koepke
(1904 - 1986)
The proposed relationship of Walter Koepke as the father of
John Koepke and
Ann Koepke is supported by DNA evidence indicating shared ancestry within the family lines.
Specifically, DNA evidence confirms a 1st cousin, twice removed relationship between JL (a descendant of the John Koepke ancestral line) and CR (a descendant of the Ann Koepke ancestral line) with a shared segment of 288.69 cM across 14 HIR segments.
This match is consistent with their placement within these shared ancestral branches.
