No trace of John or Abigail has been found in Charlestown, but:

* A list of letters remaining in the Post Office at Newport, Sept 13, 1762 includes Abigail Langworthy. The only known candidate is John’s wife. (The Newport Mercury, Sept 14, 1762)

* Abigail Langworthy and a male older than 16 appear in the 1774 census of Newport, Rhode Island. Again, John’s wife is the only known candidate for this Abigail. So this web site proposes that the Langworthys in this census are John’s widow and son John.
