The maternal relationship between Katharina Klassen and her daughter
Catherine Dueck is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DJG.
The segmental (via DNA segment triangulation) and total DNA shared between DJG and other confirmed descendants of
Paul Schellenberg is consistent with the expected ranges for their respective relationships. Since DJG descends from Paul Schellenberg through Katharina Klassen and her daughter Catherine Dueck, the presence of significant shared DNA between DJG and other known descendants of Paul Schellenberg validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA Paul Schellenberg through Katharina Klassen to Catherine Dueck, and ultimately to DJG, confirming this direct ancestral connection through multiple generations.
