The paternal relationship between Edward Fredericks and his son
Roy 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
Naoma Greene is consistent with the expected ranges for their respective relationships. Since LC descends from Naoma Greene through Edward Fredericks and his son Roy Fredericks, the presence of significant shared DNA between LC and other known descendants of Naoma Greene validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA Naoma Greene through Edward Fredericks to Roy Fredericks, and ultimately to LC, confirming this direct ancestral connection through multiple generations.
