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