Around 1745-1748, the merchant Alexander Johnston sent Francis Newton (d. 1805), a clerk, to the island of Madeira, where Newton established a wine-trading firm. Around 1758, Newton entered into a partnership with Thomas Gordon, another of Johnston's protégés. Other partners included William Johnston, Thomas Murdoch, and a man by the name of Scott. Their agent Thomas Newton was based in New York City in the 1760s and 1770s. The firm was later known as Newton, Gordon, Cossart & Co. and Cossart, Gordon & Co.
