In short: There is a separate Zebediah Farnham from Windham, Conn. which I think is getting mixed up with our Zebediah Farnum of Andover Mass. and Concord NH.
It appears this FindAGrave which is being used is the wrong guy's grave, and the wrong dates.

The correct Zebediah Farnum for THIS profile is that which is born of Ephraim & Priscilla in Andover, Mass, married to Mary Walker, before moving with much family to Concord, NH. Had son John Farnum in Concord NH (and others, but definitely John).
