Dietrich Thiessen (22 Aug 1823 - 24 May 1879)

The proposed relationship of Dietrich Thiessen as the father of Elisabeth Thiessen and Dietrich H. Thiessen is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a 3rd cousin, once removed relationship between LRY (a descendant of the Dietrich H. Thiessen ancestral line) and JWF (a descendant of the Elisabeth Thiessen ancestral line) with a shared segment of 46.96 cM across 2 HIR segments.

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