The maternal relationship between Maude Gertrude Griggs and her daughter
Nancy Powers is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CG.
The segmental (via DNA segment triangulation) and total DNA shared between CG and other confirmed descendants of
William Cragg/
Charlotte Selby is consistent with the expected ranges for their respective relationships. Since CG descends from William Cragg/Charlotte Selby through Maude Gertrude Griggs and her daughter Nancy Powers, the presence of significant shared DNA between CG 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 Maude Gertrude Griggs to Nancy Powers, and ultimately to CG, confirming this direct ancestral connection through multiple generations.
