The maternal relationship between Mary Marriner BRIGHT and her son George William Arnold is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JA.

The segmental (via DNA segment triangulation) and total DNA shared between JA and other confirmed descendants of Edmund BRIGHT/Mary KNIGHTON is consistent with the expected ranges for their respective relationships. Since JA descends from Edmund BRIGHT/Mary KNIGHTON through Mary Marriner BRIGHT and her son George William Arnold, the presence of significant shared DNA between JA and other known descendants of Edmund BRIGHT/Mary KNIGHTON validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Edmund BRIGHT/Mary KNIGHTON through Mary Marriner BRIGHT to George William Arnold, and ultimately to JA, confirming this direct ancestral connection through multiple generations.
