The paternal relationship between Jack Harold Schonfeld and his son Charles Schonfeld is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DS.

The segmental (via DNA segment triangulation) and total DNA shared between DS and other confirmed descendants of Harold John Schonfeld/Angeline Johanna Beckman is consistent with the expected ranges for their respective relationships. Since DS descends from Harold John Schonfeld/Angeline Johanna Beckman through Jack Harold Schonfeld and his son Charles Schonfeld, the presence of significant shared DNA between DS and other known descendants of Harold John Schonfeld/Angeline Johanna Beckman validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Harold John Schonfeld/Angeline Johanna Beckman through Jack Harold Schonfeld to Charles Schonfeld, and ultimately to DS, confirming this direct ancestral connection through multiple generations.
