The maternal relationship between Grace Brauer and her son CR is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AS.
The segmental (via DNA segment triangulation) and total DNA shared between AS and other confirmed descendants of
Wilhelm Carl Hackbarth/
Anna Dorothea Hafemann is consistent with the expected ranges for their respective relationships. Since AS descends from Wilhelm Carl Hackbarth/Anna Dorothea Hafemann through Grace Brauer and her son CR, the presence of significant shared DNA between AS and other known descendants of Wilhelm Carl Hackbarth/Anna Dorothea Hafemann validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Wilhelm Carl Hackbarth/Anna Dorothea Hafemann through Grace Brauer to CR, and ultimately to AS, confirming this direct ancestral connection through multiple generations.
