The maternal relationship between Rachel Wright and her son James Coates is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RLB.

The segmental (via DNA segment triangulation) and total DNA shared between RLB and other confirmed descendants of John C Wright/Rachel Wells is consistent with the expected ranges for their respective relationships. Since RLB descends from John C Wright/Rachel Wells through Rachel Wright and her son James Coates, the presence of significant shared DNA between RLB and other known descendants of John C Wright/Rachel Wells validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple John C Wright/Rachel Wells through Rachel Wright to James Coates, and ultimately to RLB, confirming this direct ancestral connection through multiple generations.
