The maternal relationship between Mary Elizabeth Wellborn and her son
Mark Joseph Griggs is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KGS.
The segmental (via DNA segment triangulation) and total DNA shared between KGS and other confirmed descendants of
William Cragg/
Charlotte Selby is consistent with the expected ranges for their respective relationships. Since KGS descends from William Cragg/Charlotte Selby through Mary Elizabeth Wellborn and her son Mark Joseph Griggs, the presence of significant shared DNA between KGS and other known descendants of William Cragg/Charlotte Selby validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple William Cragg/Charlotte Selby through Mary Elizabeth Wellborn to Mark Joseph Griggs, and ultimately to KGS, confirming this direct ancestral connection through multiple generations.
