The maternal relationship between Mary Elizabeth Overby and her daughter
Anna Elizabeth Burton is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MD.
The segmental (via DNA segment triangulation) and total DNA shared between MD and other confirmed descendants of
James Alexander Short/
Elizabeth Moore is consistent with the expected ranges for their respective relationships. Since MD descends from James Alexander Short/Elizabeth Moore through Mary Elizabeth Overby and her daughter Anna Elizabeth Burton, the presence of significant shared DNA between MD and other known descendants of James Alexander Short/Elizabeth Moore validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple James Alexander Short/Elizabeth Moore through Mary Elizabeth Overby to Anna Elizabeth Burton, and ultimately to MD, confirming this direct ancestral connection through multiple generations.
