The paternal relationship between Clair Ellsworth Cook and his daughter DS 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 Clair Ellsworth Cook and his daughter DS, 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 Clair Ellsworth Cook to DS, and ultimately to DS, confirming this direct ancestral connection through multiple generations.
