The maternal relationship between Amalie Hackbarth and her son Fredrick Beversdorf is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant FB.

The segmental (via DNA segment triangulation) and total DNA shared between FB and other confirmed descendants of Wilhelm Carl Hackbarth/Anna Dorothea Hafemann is consistent with the expected ranges for their respective relationships. Since FB descends from Wilhelm Carl Hackbarth/Anna Dorothea Hafemann through Amalie Hackbarth and her son Fredrick Beversdorf, the presence of significant shared DNA between FB 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 Amalie Hackbarth to Fredrick Beversdorf, and ultimately to FB, confirming this direct ancestral connection through multiple generations.
