The paternal relationship between Stephen Tompkins and his son Cornelius Tompkins 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 Tompkins II/Rebecca Knight is consistent with the expected ranges for their respective relationships. Since MC descends from John Tompkins II/Rebecca Knight through Stephen Tompkins and his son Cornelius Tompkins, the presence of significant shared DNA between MC and other known descendants of John Tompkins II/Rebecca Knight validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple John Tompkins II/Rebecca Knight through Stephen Tompkins to Cornelius Tompkins, and ultimately to MC, confirming this direct ancestral connection through multiple generations.
