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