The maternal relationship between Harriet Lucy Morse and her daughter Adele Sumner Davis is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KLJ.

The segmental (via DNA segment triangulation) and total DNA shared between KLJ and other confirmed descendants of William Noyes/AP is consistent with the expected ranges for their respective relationships. Since KLJ descends from William Noyes/AP through Harriet Lucy Morse and her daughter Adele Sumner Davis, the presence of significant shared DNA between KLJ and other known descendants of William Noyes/AP validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple William Noyes/AP through Harriet Lucy Morse to Adele Sumner Davis, and ultimately to KLJ, confirming this direct ancestral connection through multiple generations.
