The paternal relationship between John Tompkins I and his son
John Tompkins II is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant
Barbara Joyce Meeker.
The segmental (via DNA segment triangulation) and total DNA shared between Barbara Joyce Meeker and other confirmed descendants of
Ralph Tomkins/
Katherine Foster is consistent with the expected ranges for their respective relationships. Since Barbara Joyce Meeker descends from Ralph Tomkins/Katherine Foster through John Tompkins I and his son John Tompkins II, the presence of significant shared DNA between Barbara Joyce Meeker and other known descendants of Ralph Tomkins/Katherine Foster validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Ralph Tomkins/Katherine Foster through John Tompkins I to John Tompkins II, and ultimately to Barbara Joyce Meeker, confirming this direct ancestral connection through multiple generations.
