The maternal relationship between Elizabeth E. Albertson and her daughter Mary M. Couch is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant SM.

The segmental (via DNA segment triangulation) and total DNA shared between SM and other confirmed descendants of John Albertson/Elizabeth Hunter is consistent with the expected ranges for their respective relationships. Since SM descends from John Albertson/Elizabeth Hunter through Elizabeth E. Albertson and her daughter Mary M. Couch, the presence of significant shared DNA between SM and other known descendants of John Albertson/Elizabeth Hunter validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple John Albertson/Elizabeth Hunter through Elizabeth E. Albertson to Mary M. Couch, and ultimately to SM, confirming this direct ancestral connection through multiple generations.
