Jedediah4 Austin (son of Edward4) b circa 1730-35 (place not stated) probably married before 1653 and unknown wife and married second to Ann King on 3 Feb 1756 in Charlestown, RI. She was the daughter of Widow Ann King. (this implies that his son Silas was son of the first unknown wife and not his second wife)
The Rhode Island Historical Cemeteries Transcription Project has a Jedediah Austin found in WY502, or Austin Ground, Westerly, Rhode Island. It lists the directions as *LOST* Route #3? at TEL. pole # 6248. There is no birth or death information given in the listing and he is the only Austin that I can find as buried in WY502. I have not made an extensive search for what other names may be in WY502 as the listings are by last name, not by cemeteries, nor is there any indication that this the same Jedediah Austin as in this page, but it is worth further research.
