The paternal relationship between William Watson and his son James B. 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 William Watson and his son James B. 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 William Watson to James B. Watson, and ultimately to JD, confirming this direct ancestral connection through multiple generations.
