The grave marker of which Bounty mutineer is on display in the National Maritime Museum in Greenwich, London UK?

The grave marker of John Adams, the last surviving mutineer from the HMS Bounty mutiny, is on display at the National Maritime Museum in Greenwich, London.

Adams was one of the mutineers who took part in the famous 1789 mutiny led by Fletcher Christian against Captain William Bligh. After the mutiny, Adams and the others settled on Pitcairn Island, where Adams lived for the rest of his life. His grave marker, which was originally on Pitcairn Island, was removed and brought to Britain by Rear-Admiral Sir Fairfax Moresby who visited the island in August 1852.
