The maternal relationship between Inez Leila Rorabaugh and her daughter Josephine Lura Davis is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CJL.

The segmental (via DNA segment triangulation) and total DNA shared between CJL and other confirmed descendants of Jacob Carner/Sarah Ellen Albertson is consistent with the expected ranges for their respective relationships. Since CJL descends from Jacob Carner/Sarah Ellen Albertson through Inez Leila Rorabaugh and her daughter Josephine Lura Davis, the presence of significant shared DNA between CJL and other known descendants of Jacob Carner/Sarah Ellen Albertson validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Jacob Carner/Sarah Ellen Albertson through Inez Leila Rorabaugh to Josephine Lura Davis, and ultimately to CJL, confirming this direct ancestral connection through multiple generations.
