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