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