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