A couple of extra pieces of information. Hepzibah Brown Abbott died 20 May 1790 in Woodstock and there is a record of that death. Nathan the son of Nathan and Eunice died in 1794 at Woodstock. There is a probate record from 1794 for Nathan (1744-1794) and his widow Judith and son Alba are administrators of the estate. I really question whether Nathan and Hepzibah are the parents of John who I have seen a birth date of 1781. Hepzibah died in 1790 at age 64 and she seems to be the Hepzibah for whom there is a 1726 birth record in Pomfret. I have seen two somewhat younger sons (born in the early 1760's) attributed to them but actually have not seen a record of that.
