Morgan Rattler was probably a French vessel launched under another name and taken in prize early in 1793 after the outbreak of the French Revolutionary Wars. She became a Liverpool privateer, but was quickly captured. A few years later she became a French privateer. She captured several British merchantmen before a British naval brig captured her and her prizes.

Two vessels have been named Biscayneer, which generally means a sailor or a ship from Biscay:
Molly was launched at Liverpool in 1770. Between 1777 and 1779 she made three voyages to the British northern whale fishery. Afterwards, she sailed as a West Indiaman. From 1779 she sailed under a letter of marque, and captured one prize. Around the end of 1781 she engaged in a single ship action in which her captain was killed. She was captured but her captor gave her up. She was last listed in 1783.

In 1779 she repelled an American privateer in a sanguinary single ship action. Her owners renamed her Lydia. While trading with Tortola she captured one or two prizes. Lydia was herself captured in 1782.
Hercules was launched at Bristol in 1796 as a West Indiaman. In 1815 A United States privateer captured her but the Royal Navy recaptured her. Because the recapture occurred after 1 March 1815, she was returned to the United States.
Woolton, was launched at King's Lynn in 1773 as Narr. By 1775 she was sailing between London and Liverpool as Woolton. A French privateer captured and ransomed her in September 1779. In 1781 she sailed briefly as a privateer and made one notable capture that involved a single ship action. After the war Woolton continued to trade primarily between London and Liverpool until she was wrecked in 1785.
Chaser first appeared under that name in British records in 1786. She had been launched in 1771 at Philadelphia under another name, probably Lord North. Lord North became Cotton Planter, and then Planter, before she became Chaser. Between 1786 and 1790 Chaser made four voyages as a whaler in the British southern whale fishery. She then became a merchantman. In 1794 a privateer captured her but the Spanish recaptured her. She became a Liverpool-based slaver. In 1796 she was condemned in West Africa on her first voyage in the triangular trade before she could embark any enslaved people.
