The maternal relationship between Katharina Schellenberg and her son
Franz Janzen is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant TNP.
The segmental (via DNA segment triangulation) and total DNA shared between TNP and other confirmed descendants of
Paul Schellenberg is consistent with the expected ranges for their respective relationships. Since TNP descends from Paul Schellenberg through Katharina Schellenberg and her son Franz Janzen, the presence of significant shared DNA between TNP 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 Schellenberg to Franz Janzen, and ultimately to TNP, confirming this direct ancestral connection through multiple generations.
