Haym Salomon. Haym Salomon (also Solomon; April 7, 1740 â January 6, 1785) was a Polish-born American Jewish businessman and political financial broker who immigrated to New York City from Poland during the period of the American Revolution.
Solomons is located at the southern tip of Calvert County, in Southern Maryland, where the Patuxent River meets the Chesapeake Bay. The island itself was variously known as Bourneâs Island (about 1680), Somervellâs Island (1740- 1814) and Sandy Island (1827- 1865). The land was most likely part of the early land grant of Eltonhead Manor.
