The maternal relationship between Edna Ellen Carpenter and her daughter Ethel Mae Blake is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DR.

The segmental (via DNA segment triangulation) and total DNA shared between DR and other confirmed descendants of Edward S. Carpenter/Eleanor 'Ellen' House is consistent with the expected ranges for their respective relationships. Since DR descends from Edward S. Carpenter/Eleanor 'Ellen' House through Edna Ellen Carpenter and her daughter Ethel Mae Blake, the presence of significant shared DNA between DR and other known descendants of Edward S. Carpenter/Eleanor 'Ellen' House validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Edward S. Carpenter/Eleanor 'Ellen' House through Edna Ellen Carpenter to Ethel Mae Blake, and ultimately to DR, confirming this direct ancestral connection through multiple generations.
