Admiral Kingsmill appeared in Lloyd's Register for 1797 as a British clinker-built and Cork-based privateer.

[1] Captain Eleazer Thornton acquired a letter of marque for Admiral Kingsmill on 19 December 1796.

It gave her burthen as 160 tons and her trade as Liverpool-Africa, indicating that she was probably a slave ship.

A database of slave-trading voyages showed her master as Hugh Kessick, and her owners as James Penny, James Penny, Jr., Moses Benson, and John Backhouse.

She left Liverpool on 8 June 1797 and gathered her slaves from West Central Africa.
