The maternal relationship between Mary Elizabeth Albertson and her son Joseph Lawrence McAndrews is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant EL.

The segmental (via DNA segment triangulation) and total DNA shared between EL and other confirmed descendants of John Albertson/Elizabeth Hunter is consistent with the expected ranges for their respective relationships. Since EL descends from John Albertson/Elizabeth Hunter through Mary Elizabeth Albertson and her son Joseph Lawrence McAndrews, the presence of significant shared DNA between EL 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 Mary Elizabeth Albertson to Joseph Lawrence McAndrews, and ultimately to EL, confirming this direct ancestral connection through multiple generations.
