The maternal relationship between Augusta Grade and her daughter
Mathilda Baumann is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CL.
The segmental (via DNA segment triangulation) and total DNA shared between CL and other confirmed descendants of AG/
Louise Wilhelmine Glander is consistent with the expected ranges for their respective relationships. Since CL descends from AG/Louise Wilhelmine Glander through Augusta Grade and her daughter Mathilda Baumann, the presence of significant shared DNA between CL and other known descendants of AG/Louise Wilhelmine Glander validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple AG/Louise Wilhelmine Glander through Augusta Grade to Mathilda Baumann, and ultimately to CL, confirming this direct ancestral connection through multiple generations.
