The maternal relationship between Adda Cable and her son Walter Lee Jr is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant GS.

The segmental (via DNA segment triangulation) and total DNA shared between GS and other confirmed descendants of AC/SS is consistent with the expected ranges for their respective relationships. Since GS descends from AC/SS through Adda Cable and her son Walter Lee Jr, the presence of significant shared DNA between GS and other known descendants of AC/SS validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple AC/SS through Adda Cable to Walter Lee Jr, and ultimately to GS, confirming this direct ancestral connection through multiple generations.
