The paternal relationship between August Tesch and his daughter
Ella Tesch is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RD.
The segmental (via DNA segment triangulation) and total DNA shared between RD and other confirmed descendants of FH is consistent with the expected ranges for their respective relationships. Since RD descends from FH through August Tesch and his daughter Ella Tesch, the presence of significant shared DNA between RD 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 August Tesch to Ella Tesch, and ultimately to RD, confirming this direct ancestral connection through multiple generations.
