The paternal relationship between Joseph Cook and his son
John Cook 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
John C Wright/
Rachel Wells is consistent with the expected ranges for their respective relationships. Since DS descends from John C Wright/Rachel Wells through Joseph Cook and his son John Cook, the presence of significant shared DNA between DS and other known descendants of John C Wright/Rachel Wells validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple John C Wright/Rachel Wells through Joseph Cook to John Cook, and ultimately to DS, confirming this direct ancestral connection through multiple generations.
