The paternal relationship between Roy Fredericks and his son William Henry Fredericks is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant LC.

The segmental (via DNA segment triangulation) and total DNA shared between LC and other confirmed descendants of TF/Naoma Greene is consistent with the expected ranges for their respective relationships. Since LC descends from TF/Naoma Greene through Roy Fredericks and his son William Henry Fredericks, the presence of significant shared DNA between LC and other known descendants of TF/Naoma Greene validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple TF/Naoma Greene through Roy Fredericks to William Henry Fredericks, and ultimately to LC, confirming this direct ancestral connection through multiple generations.
