Two Sisters was launched in 1797 in Nova Scotia and in 1804 shifted her registry to the United Kingdom.

[2] Lloyd's List (LL) reported in September 1804 that the French privateer Uncle Thomas had captured at 40°30′N 25°10′W / 40.500°N 25.167°W / 40.500; -25.167 two vessels, Mary, of Greenock, which had been sailing to Virginia, and Two Sisters, of Dartmouth, which had been sailing from Newfoundland.

[4][b] The French prize master sailed Two Sisters for Ushant.

As she approached the port the French prize crew sighted some sails that they thought might be British naval vessels, and took to her boats, abandoning her, and her mate and a boy who had been part of the original crew and whom the French had kept on board.

[7] The entry in LR carried the notation "captured", but struck through.
