The maternal relationship between Sarah Frances Pennington and her son DKWCJWOCI is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CI.
The segmental (via DNA segment triangulation) and total DNA shared between CI and other confirmed descendants of
Timothy Pennington/
Nancy Susannah Riggs is consistent with the expected ranges for their respective relationships. Since CI descends from Timothy Pennington/Nancy Susannah Riggs through Sarah Frances Pennington and her son DKWCJWOCI, the presence of significant shared DNA between CI and other known descendants of Timothy Pennington/Nancy Susannah Riggs validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Timothy Pennington/Nancy Susannah Riggs through Sarah Frances Pennington to DKWCJWOCI, and ultimately to CI, confirming this direct ancestral connection through multiple generations.
