The maternal relationship between Mary Amanda Waddill and her son Abram Wesley Johnson is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant ES.

The segmental (via DNA segment triangulation) and total DNA shared between ES and other confirmed descendants of John Waddill is consistent with the expected ranges for their respective relationships. Since ES descends from John Waddill through Mary Amanda Waddill and her son Abram Wesley Johnson, the presence of significant shared DNA between ES and other known descendants of John Waddill validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA John Waddill through Mary Amanda Waddill to Abram Wesley Johnson, and ultimately to ES, confirming this direct ancestral connection through multiple generations.
