A number of vessel were named Caroline:
HMS Nimrod was a brig-sloop of the British Royal Navy, launched in 1812. She spent her war years in north American waters where she captured one small privateer, assisted in the capture of another, and captured or destroyed some 50 American vessels. After the war she captured smugglers and assisted the civil authorities in maintaining order in Tyne. She was wrecked in 1827 and so damaged that the Navy decided she was not worth repairing. A private ship-owner purchased Nimrod and repaired her. She then went on to spend some 20 years trading between Britain and Charleston, the Mediterranean, Australia, and India. She was last listed in 1851.
Young William was a ship launched in 1794 at Whitby, Yorkshire, England. She made a voyage to Botany Bay for the British East India Company (EIC), and then on her way to China discovered or rediscovered several Pacific Islands. Later, she made two voyages as a slave ship. She was wrecked in September 1802.
Betsy was launched at Lancaster in 1793 as a West Indiaman. In 1801 she made one voyage for the British East India Company (EIC) to bring back rice at the behest of the British government. On her return she became a Baltic trader. She was lost in 1803.
Latona was launched in 1786 at Newcastle upon Tyne. She spent her entire career as a merchantman. In 1800 a privateer captured her, but a British privateer recaptured her quickly. She was wrecked in 1835.
HMS Mastiff was launched at Hull in 1790, as Herald. From there she traded with the Baltic. The British Royal Navy purchased her in 1797, had her fitted at Leith, and named her GB №35, and then Mastiff. She served as a convoy escort in the North Sea until she wrecked in 1800.
Liberty was built at Broadstairs in 1784 as a West Indiaman. She made one voyage to the West Indies for the British East India Company (EIC) in 1795. A French squadron burnt her at Montserrat in 1805
Recovery was built at Liverpool in 1793. She was a West Indiaman that sailed under a letter of marque. The French privateer Courageaux captured her in 1799. She returned to British ownership by 1800 and continued to trade until she foundered in June 1818 on her way from Hull to Miramichi Bay.
Gallant Schemer was launched in 1799 at Falmouth. A French privateer captured her in 1805, but she was back in British hands by 1808. She then traded with South America and the Mediterranean. A French privateer captured her in 1813.
Lady Harewood, was launched in 1791 at Rotherhithe. She was initially a West Indiaman and in 1800 a French privateer captured her, but a Royal Navy frigate recaptured her two days later. She made three voyages transporting convicts to Australia, one in 1829 to Van Diemen's Land, and two, in 1831 and 1832, to New South Wales. In 1833 she became leaky on her way to Singapore from Australia and was condemned and sold at Singapore.
Caledonian was launched at Barnstaple in 1811 as a West Indiaman. She first appeared in Lloyd's Register (LR) in 1811 with William Lund, master, William Scott owner, and trade Bristol–Jamaica. She made two voyages to Jamaica, and foundered at sea on 5 July 1813 homeward bound to Bristol, from Jamaica, on her second. A more complete account reports that she had suffered damage, losing her bowsprit, foremast, and main topmast. After she had parted from the rest of the convoy her crew abandoned her.
Harpooner was launched at Whitby in 1769, or possibly a few years later. Her early career is obscure. She may have been a Greenland whaler between 1786 and 1792. She appeared in Lloyd's Register in 1801, and thereafter traded across the Atlantic. She was wrecked in 1816 with heavy loss of life.
Sir James Henry Craig was launched in Quebec in 1811. She first appeared in Lloyd's Register (LR) in 1813 and then spent much of her career sailing between Britain and Canada. She was lost on 4 December 1829.
Earl Fauconberg was launched at Whitby in 1765. From 1784 on she made numerous voyages as a Greenland whaler. She was lost there in 1821.
Aurora was launched at Kingston upon Hull. She traded with the Baltic until 1803 when she became a Greenland whaler. She was lost in 1821 on her 18th voyage to the northern whale fishery.
Sarah Ann, was a ship launched at Philadelphia in 1795. A French privateer captured her, but she was recaptured and sold. She returned to service and was last listed in 1806.
Rachel was launched at Bristol in 1795. She spent most of her career as a constant trader, sailing to and from Nevis. A French privateer captured her in 1803 but a Liverpool letter of marque quickly recaptured her. She was wrecked in July 1811.
Princess Charlotte was launched in 1814 at Bristol. She spent almost all of her career as a West Indiaman though she did make voyages to North America and Africa. In 1848 she was sold for breaking up.
Trelawney was launched in 1775 at Liverpool as Clayton, sailing as a West Indiaman. She first appeared as Trelawney in 1779. Between early 1788 and end-1790 she made two voyages as a whaler in the northern whale fishery, and one in the southern whale fishery. She disappeared from the registers between 1794 and 1800. In 1800 she reappeared as a coaster, sailing between the River Tyne and London. In 1809 she started sailing across the North Atlantic to Halifax, Nova Scotia, and Quebec. A United States privateer captured her in 1812.
Achilles was built at Sunderland in 1799. Although early on she made some voyages to the West Indies, she spent most of her mercantile career trading with the Baltic and northern Russia, and as a coaster. However, between about 1810 and 1814, she served as a transport under Transport Board. She suffered three maritime mishaps before 1835 and assisted at a fourth. She was lengthened in 1835. Her crew abandoned her in October 1839 and she subsequently foundered.
