The Last Account I heard of Widdicombe he was well but very narrowly escaped drowning in the Boat at Norfolk Island he was the only person saved out of 5. One of them was a Midshipman belonging to this Ship. 
In July 1791 Richard had 1 acre of land at Sydney Town (Kingston).  Richard left Norfolk Island aboard the Chesterfield in Mar 1793, he was on the stores for his entire time on Norfolk Island. No further records found in the Colony regarding Richard Widdicombe. He most likely stayed with Chesterfield for it journey to Bengal India as his sentence had expired.
