The maternal relationship between Margaretha Niebuhr and her son
Herman "harm" Neufeld is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant ADN.
The segmental (via DNA segment triangulation) and total DNA shared between ADN and other confirmed descendants of
Jacob Schellenberg/
Christina "stiencke" Loewen is consistent with the expected ranges for their respective relationships. Since ADN descends from Jacob Schellenberg/Christina "stiencke" Loewen through Margaretha Niebuhr and her son Herman "harm" Neufeld, the presence of significant shared DNA between ADN and other known descendants of Jacob Schellenberg/Christina "stiencke" Loewen validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Jacob Schellenberg/Christina "stiencke" Loewen through Margaretha Niebuhr to Herman "harm" Neufeld, and ultimately to ADN, confirming this direct ancestral connection through multiple generations.
