Quick thought (and for future reference this is just a theory), could Jane Champion (buried in Westcott Free Burying Ground) have married first Daniel Frazier (buried next to Jane) having one son c.1788 named Daniel (who married Sarah Matlack) and then married Hezediah Champion having Lovina, Lorana, and Federal. Mary (x) Vanmeter, could in this scenario be either a Champion or a Frazier. Susannah was however a Frazier and in that case her age might be a little off online (as they often are).
I'm fairly certain that Daniel Frazier's (d1791) wife was a Jane because just when Daniel dissappears from tax records a Jane appears from 1791 to 1793 and then dissappears.
Perhaps property records and more wills could shed light.
