The paternal relationship between Isaac Cook and his son
John Cook is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant ECS.
The segmental (via DNA segment triangulation) and total DNA shared between ECS and other confirmed descendants of
John C Wright/
Rachel Wells is consistent with the expected ranges for their respective relationships. Since ECS descends from John C Wright/Rachel Wells through Isaac Cook and his son John Cook, the presence of significant shared DNA between ECS 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 Isaac Cook to John Cook, and ultimately to ECS, confirming this direct ancestral connection through multiple generations.
