The maternal relationship between Wilhelmine Friederike Hackbarth and her son
John Heitmann is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant EL.
The segmental (via DNA segment triangulation) and total DNA shared between EL and other confirmed descendants of FH is consistent with the expected ranges for their respective relationships. Since EL descends from FH through Wilhelmine Friederike Hackbarth and her son John Heitmann, the presence of significant shared DNA between EL 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 Wilhelmine Friederike Hackbarth to John Heitmann, and ultimately to EL, confirming this direct ancestral connection through multiple generations.
