[Robert S. Grumet (2014)] variant spelling of sewan, a word that Delawares and their neighbors used for wampum. The name first appeared as Sywanois fixed onto a location in present-day southeastern Massachusetts noted in Adriaen Block’s 1614 map (Stokes 1915-1928 1: Color Plate 1). Slightly rewording the name in the 1625 edition of his book, Johan de Laet (in Jameson 1909:44) wrote that Indian people calling themselves Siwanois lived along the north shore of Long Island Sound “for eight leagues, to the neighborhood of Hellegat” (modern Hellgate across from Manhattan on the East River). Ruttenber (1872:81-82) followed De Laet when he proposed the existence of a Siwanoy chieftaincy stretching along the north shore of Long Island Sound from New Haven to Manhattan. Anthropologist James E. Mooney (in Hodge 1907-1910 2:913) thought that people belonging to Ruttenber’s Siwanoy chieftaincy were members of a Wappinger Confederacy uniting all Indian communities between the Hudson and Connecticut river valleys. Although both identifications are still widely accepted, no sources from the colonial era mention a Siwanoy chieftaincy, a Wappinger Confederacy, or any individual belonging to groups identified by these names. The name Siwanoy today graces a street and school on the New York–Connecticut border, a country club in Bronxville, and the two-mile-long Siwanoy Trail in Pelham Bay Park in the Bronx. STISSING (Dutchess County). Stissing Mountain (elevation 1,403 feet) is a prominent high point where the borders of the towns of name to symbolize its commitment to preserving the area’s natural and cultural history. SUCCESS (Nassau County). Lake Success is a glacial kettle hole located in the Village of the same name (incorporated 1926) in the Town of North Hempstead. The name may well be a developer’s conflation of the attractive word “success” with an appealingly romantic Indian association provided by memories of Suscoe’s Wigwam located nearby during colonial times. Situated in adjacent Matinecock Neck (see above), Suscoe’s Wigwam was long regarded as the home of the prominent Matinecock sachem Suscaneman (Grumet 1996). The somewhat more distant Ciscascata (see Syosset below) is the only other Indian place name resembling Success in colonial records in the area. The shores of Lake Success briefly served as the temporary headquarters of the United Nations between 1946 and 1951. Today, Lake Success is mainly a community of residential neighborhoods and corporate campuses. It is difficult to know what role, if any, New York’s Lake Success has had in the creation of the 117 places named Success listed in the GNIS (see in Part 3). Some, such as places named Lake Success in California, New Jersey, and Washington, may be direct transfers. Others, including several historical locales no longer gracing modern-day maps, probably express the hopes of their creators. SYOSSET (Nassau County). Whritenour thinks that the earliest recorded form of this name, Ciscascata, sounds like a Munsee word, *asiiskuwaskat, “it is muddy grass.” Tooker (1911:255-256) suggested that Syosset represented what he thought was the way the name Schouts Bay (Dutch for sheriff, subsequently renamed Manhasset Bay, an import from eastern Long Island) sounded to local Indian ears. Today, Syosset is a residential community in Oyster Bay. Ciscascata initially appeared in an Indian deed to land in the area signed on May 20, 1648 (Cox 1916-1940 1:625-626). Colonists called the place East Woods. Postal authorities briefly revived a version of Ciscascata, respelled Syosset, as the name they gave to the post office that operated at Oyster Bay from 1846 to 1848. Nearby Glen Cove took up the name Syosset for one week before changing it back (French 1860:550). The name finally stuck in 1854, when the Long Island Railroad opened its Syosset Station at what is now the community’s village center. TACKAMACK (Rockland County). Whritenour thinks that the name of present-day Tackamack Park in Orangetown sounds like a Munsee word, *ptukameekw, “round fish.” The name is thought to be a much-altered form of Raikghawaik, another Munsee word that Whritenour thinks resembles *leexaweek, “that which forks.” The latter word was first mentioned in 1709 as the name of a tributary of the Saddle River called Hohokus Brook (see above), that some settlers used to identify the entire Saddle River system (Wardell Beyond Manhattan, Robert S. Grumet 2009:93). The name Tackamack was given to the park when it was Tatomuck in Connecticut for further information. established on former estate land atop Clausland Mountain acquired by the Town of Orangetown in 2003. TITICUS (Westchester County). In New York, Titicus is the name of a mountain, a dam, a reservoir created by the dam, and the river TACKAPAUSHA (Nassau County). Tackapausha Preserve (ac- flowing into the impoundment from Connecticut.
