Masters & Markoe.

Thomas Masters (d. 1844) was a British merchant who established himself in the United States about 1803. By 1807 he was a clerk in the mercantile house of Pratt & Kintzing. The next year he left to establish his own mercantile house. In 1810 he formed a partnership with his brother-in-law, Francis Markoe. Much of Markoe & Master's business involved the West Indian trade. Severe losses caused by the War of 1812 caused the dissolution of the firm on November 14, 1814. Thomas Masters then associated himself with the New York merchant Divie Bethune.

Masters & Markoe then operated in New York from about 1825 until 1836, when the firm became Masters, Markoe & Co. Thomas Masters and Francis Markoe were joined, at different times, by their sons, Samuel Caldwell Masters and Francis Markoe, Jr., and by Jeremiah Wilbur, a son-in-law of Msters. The firm of Masters, Markoe & Co. continued until 1846, when it became Markoe, Wilbur & Scott.
