The maternal relationship between Sarah Delong and her son John Carpenter is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant MC.

The segmental (via DNA segment triangulation) and total DNA shared between MC and other confirmed descendants of John Francis Delong/Sarah Winteringer is consistent with the expected ranges for their respective relationships. Since MC descends from John Francis Delong/Sarah Winteringer through Sarah Delong and her son John Carpenter, the presence of significant shared DNA between MC and other known descendants of John Francis Delong/Sarah Winteringer validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple John Francis Delong/Sarah Winteringer through Sarah Delong to John Carpenter, and ultimately to MC, confirming this direct ancestral connection through multiple generations.
