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 RDC.
The segmental (via DNA segment triangulation) and total DNA shared between RDC and other confirmed descendants of
John Francis Delong/
Sarah Winteringer is consistent with the expected ranges for their respective relationships. Since RDC descends from John Francis Delong/Sarah Winteringer through Sarah Delong and her son John Carpenter, the presence of significant shared DNA between RDC 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 RDC, confirming this direct ancestral connection through multiple generations.
