Several ships have borne the name Duke of Clarence, named for one or another Duke of Clarence, originally Prince William, the first Duke of Clarence and St Andrews, who acceded to the throne as William IV of the United Kingdom, but later the Duke of Clarence and Avondale:
Tobago was a ship launched in 1790. She came into British hands in 1793 and was probably a prize taken immediately after the outbreak of the French Revolutionary Wars in early 1793. She traded with Tobago for several years before new owners purchased her for whaling. She made two whaling voyages to the East Coast of Africa before her owners sold her to new owners. She then made two voyages as a slave ship. She was abandoned or condemned in 1802 after having delivered her captives on her second such voyage.
Britannia, was a vessel launched in 1783 at Saltcoats, possibly under another name. She made four voyages from Liverpool as a slave ship in the triangular trade in enslaved people. She grounded at Liverpool in 1793 after the first. A French privateer captured her in 1795 during the second, and took her to Guadeloupe where the Republican Government almost certainly freed the captives. She returned to British ownership and made two more voyages as a slave ship. A French privateer captured her during her fourth voyage.
Canada was launched at King's Yard in 1779 for the Royal Navy, which sold her circa 1782 at the end of the war. Her name while in Royal Navy service is unknown as of November 2022. John St Barbe purchased her and named her Adriatic, but renamed her Canada circa 1786. She made three seal hunting and whaling voyages between 1791 and 1799 under that name. On the first of these a French privateer captured her, but a British merchant ship recaptured her. She was lost at South Georgia in 1800 on her fourth voyage to the southern whale fishery.
John Bull was a sailing ship built in 1799 at Liverpool for the slave trade. She made one voyage carrying slaves from West Africa to Jamaica. Thereafter she became a West Indiaman, trading with Jamaica. Early in this period she was a letter of marque, and captured a French merchant vessel. A little later John Bull detained an American vessel. Much later she transported female convicts to New South Wales from Cork. After she delivered her convicts she made an unsuccessful voyage as a whaler in the South Pacific. She was last listed in 1833.
HMS Duguay-Trouin was an 18-gun French privateer sloop launched in 1779 at Le Havre. Surprise captured her in 1780 and the British Royal Navy took her into service under her existing name. It sold Duguay-Trouin on 30 October 1783. She then became the West Indiaman Christopher. She captured several French merchant vessels. Later she became a Liverpool-based slave ship, making five voyages in the triangular trade in enslaved people. She was lost at Charleston in September 1804 in a hurricane.
Kingsmill was a French vessel launched in 1793 under a different name, captured in 1798, and sold to British owners who renamed her. She then became a slave ship, making three voyages from Africa to the West Indies. A French privateer captured her in 1804, but she returned to her owners in 1804. In 1807 she became a West Indiaman. In 1814 she became the first ship to trade with India under a license from the British East India Company (EIC) after the EIC lost its monopoly on British trade with India. She was badly damaged in 1821 and subsequently disappears from the registers.
Elliott was launched at Liverpool in 1783. She made ten voyages as a slave ship, carrying slaves from West Africa to the West Indies. Next, she made one voyage as a whaler. She then became a merchantman, sailing between England and South America. In November 1807 French privateers captured her.
African Queen's origins are uncertain. She was a foreign vessel, launched in 1789 or 1790, presumably under another name. She was taken in prize in 1796 and by 1797 she was sailing out of Bristol. She made one voyage to Africa during which she was captured and recaptured and then became a slave ship. She made one voyage to the West Indies as a merchant ship, and one voyage as a whaler, but was damaged in 1801 as she returned home from that whaling voyage and apparently never sailed again.
Horatio was launched in 1800 at Liverpool. She made four voyages as a slave ship in the triangular trade in enslaved people. During two of these voyages she was captured and recaptured. Shortly before the British slave trade ended she left the slave trade and sailed between Britain and South America and as a West Indiaman. She was wrecked in 1817.
Angola was launched in 1799 at Lancaster. She became a Liverpool-based slave ship that had made four voyages carrying captives from West Africa to the West Indies. The French had captured her in 1804 on her fifth voyage. Her captors renamed her Tigre, but the Royal Navy recaptured her late in 1804.
Goodrich was a schooner launched in Liverpool in 1799. Between 1799 and 1807, she made seven voyages as a slave ship in the triangular trade in enslaved people, two of them while being owned by Americans. After the Slave Trade Act 1807 ended the British slave trade she became a merchantman sailing from Guernsey. A French privateer captured her in July 1808.
Goodrich was a brig launched in Bermuda in 1793. She made three voyages between 1795 and 1799as a slave ship in the triangular trade in enslaved people. She then became a general merchantman and was wrecked in 1808.
Several vessels have been named Goodrich:
Isabella was launched in France in 1791 as the East Indiaman St Jean de Lone. Two British privateers captured her in 1793. She was sold in prize and renamed Isabella. She initially sailed as a West Indiaman and then between 1795 and 1798 made two voyages to India as an "extra" ship for the British East India Company (EIC). Afterwards, she returned to the West Indies and Baltic trades and was last listed in 1809, but with data stale since c.1802.
Several ships have been named John:
Tartar was built in Spain in 1784, almost certainly under another name. She was taken in prize and appears under British ownership in 1799. She became a slave ship sailing from Liverpool in the triangular trade in enslaved people. She was captured in late 1799 on her first enslaving voyage before she was able to embark any captives.
Agreeable was launched at Bermuda in 1786, probably under a different name. French owners acquired her at some point and sailed her as Agréable. In 1793 the British captured her. Subsequently, between 1793 and 1808, she made six voyages as a slave ship, alternating between the triangular trade in enslaved people, and sailing as a regular West Indiaman. French privateers captured her between the second and third voyages, and the third and fourth voyages, but each time the British Royal Navy recaptured her. In the case of the second capture she was in French hands long enough for them to send her out as a privateer. She herself captured an American vessel in 1808 as she was returning to Liverpool from her last enslaving voyage. After the end of British participation in trans-Atlantic enslaving trade, Agreeable traded more widely, particularly to South America. She was condemned at Buenos Aires in 1814 after running aground in the River Plate. She was repaired and continue to sail to Brazil until she returned to Liverpool in June 1819.
Backhouse was launched in 1798 at Dartmouth. In all, she made four voyages as a slave ship in the triangular trade in enslaved people. Between the second and the third, and after the fourth, she was a West Indiaman. A French privateer captured her early in 1810 as she was returning to Britain from Brazil.
Fortune was a French privateer launched at Bordeaux in 1800 and taken that same year. She immediately made one voyage as a whaler and privateer. She then made two voyages as a slave ship in the triangular trade in enslaved people. After the end of the British enslaving trade Fortune continued to trade with Africa and with South America. She was last listed in 1816.
