The closest I could find was a line of ships named HMS Temeraire (French for "reckless"), last of which actually sailed being a Bellerophon-class battleship back during WWI. The next HMS Temeraire was to be a Lion-class battleship, but she was canceled alongside her paper sisters. Since then, there have been a pair of stone frigates named HMS Temeraire, but no ship of the line has carried the name in decades.
