Jenny entered Lloyd's Register (LR) in 1784 with J. Parsons, master, Clements, owner, and trade Bristol–Newfoundland.

Some sources state that Teast employed Jenny as a slaver, carrying slaves between West Africa and Barbados.

[10] Voyage #1 (1791–1793): Captain James Baker sailed Jenny for the Pacific in the first week of October 1791, bound for Cape Verde and the South Seas.

A copy of Baker's chart of "Puerto Sidman" was retained in Spanish archives through Juan Francisco de la Bodega y Quadra.

In early August 1792, Jenny was in Clayoquot Sound where, with the Butterworth Squadron, Baker was involved in a violent conflict with Tla-o-qui-aht people of chief Wickaninnish.

[12] In mid October Baker left Nootka Sound to return to Bristol, stopping at the Columbia River.

In December 1792 William Robert Broughton, captain of HMS Chatham, part of the Vancouver Expedition, encountered Baker in the Columbia River.

The Jenny and Chatham left the river and crossed the Columbia Bar together, then parted ways.

He arranged with the British East India Company (EIC) for a license that would permit her to bring back a cargo from China after selling her furs there.

[17] Jenny did not appear in Lloyd's Register for 1795, but she reappeared in 1796 with E. Buckle, master, Teast, owner, and trade Bristol–Africa.

[3] Captain Edmund Buckle sailed Jenny for Africa on 29 February 1796 on a voyage not intended for the slave trade.

[20] Lloyd's List reported on 27 January 1797 that Jenny, Buckle, master, had been lost on Lundy Island as she was returning to Bristol from Africa.
