The U.S. ship ESMERALDA, 907 tons, was built at Brunswick, Maine, in 1849, by Robert McManus, who also served as her first master. She served in Williams & Guion's Black Star Line of sailing packets between New York and Liverpool in 1850, and, under George W. McManus, in the Blue Ball Line of New York-Liverpool packets in 1852. Originally registered at Brunswick, Maine, she received her first New York certificate of registry on 30 September 1854. I do not know anything of her later history or ultimate fate.
