The maternal relationship between Cletis Dee Murphy and her DNA tested son DS is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between DS and other confirmed descendants of
James Chapman/
Ruth Bertha Hammer is consistent with the expected ranges for their respective relationships. Since DS descends from James Chapman/Ruth Bertha Hammer through Cletis Dee Murphy, the presence of significant shared DNA between DS and other known descendants of James Chapman/Ruth Bertha Hammer validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple James Chapman/Ruth Bertha Hammer through Cletis Dee Murphy to DS, confirming this direct ancestral connection through multiple generations.
