The paternal relationship between Mark Joseph Griggs and his DNA tested daughter KGS is confirmed by the direct inheritance path of autosomal DNA.
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 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 paternal line.
This supports the conclusion that DNA was passed from MRCA couple William Cragg/Charlotte Selby through Mark Joseph Griggs to KGS, confirming this direct ancestral connection through multiple generations.
