The paternal relationship between Francis Marion Watson and his daughter Frances Melissa Watson is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JD.

The segmental (via DNA segment triangulation) and total DNA shared between JD and other confirmed descendants of Henry Watson/Sarah is consistent with the expected ranges for their respective relationships. Since JD descends from Henry Watson/Sarah through Francis Marion Watson and his daughter Frances Melissa Watson, the presence of significant shared DNA between JD and other known descendants of Henry Watson/Sarah validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Henry Watson/Sarah through Francis Marion Watson to Frances Melissa Watson, and ultimately to JD, confirming this direct ancestral connection through multiple generations.
