The paternal relationship between Carl Hafferman and his son Wilhelm Hafferman is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant SS.

The segmental (via DNA segment triangulation) and total DNA shared between SS and other confirmed descendants of LH/Friedericke Ludtke is consistent with the expected ranges for their respective relationships. Since SS descends from LH/Friedericke Ludtke through Carl Hafferman and his son Wilhelm Hafferman, the presence of significant shared DNA between SS and other known descendants of LH/Friedericke Ludtke validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple LH/Friedericke Ludtke through Carl Hafferman to Wilhelm Hafferman, and ultimately to SS, confirming this direct ancestral connection through multiple generations.
