Manhanset

Who they are & the name (incl. the “Metoac” invention caveat)

The Manhanset were the Eastern Algonquian people of Shelter Island and its satellite islands, one of the four East End peoples (with Montaukett, Shinnecock, and Corchaug). Their island’s name, Manhansack-aha-quash-awamock — “an island sheltered by islands” — is one of the most beautiful and best-attested Algonquian place-names on Long Island (recorded in Nathaniel Sylvester’s own 1680 will; translated by Tooker 1911).

Crucially, the Manhanset sachem Youghco (better known by one of his many names, Poggatacut/Pogatticut) was regarded by the English as “the great Sachem of all Long Island” — the grand sachem / chief sachem of Paumanack (eastern Long Island) and elder brother of the Montaukett sachem Wyandanch. So Shelter Island, tiny as it is, was the political head of the East End confederacy at contact.

The “Metoac” caveat (state it plainly): As with every Long Island people, “Metoac” is not a Manhanset word or nation — it is a 19th-century misreading of garbled 17th-century Dutch map labels (Matouwac / Meitowax / Metoac) that referred loosely to all of Long Island. John Strong (The Thirteen Tribes of Long Island: The History of a Myth, 1992) shows the “thirteen tribes” scheme and names like these were colonial conveniences fixed onto fluid, kin-based village communities to make land purchasable. “Manhanset” itself began as a place-name (“Munhausett” = “Sheltered Island” in the 1644 Hartford record) that the English hardened into a “tribal” label. Note also a persistent typo-trope: Martha Flint (1896) dropped the “n” to make “Manhasset,” conflating Shelter Island’s people with the unrelated western-LI place now called Manhasset — they are different.

Territory & overlay (which modern communities sit on their ground)

Manhanset country was Shelter Island itself (they occupied roughly two dozen sites across it, concentrated on wooded uplands and near the creeks and salt marshes — the Smith site near today’s Mashomack Preserve yielded hearths and house structures), plus the surrounding islands of Peconic Bay:

• Shelter Island (the whole modern town, including the villages below) → ../../shelter-island/shelter-island/
• Shelter Island Heights → ../../shelter-island/shelter-island-heights/
• Dering Harbor → ../../shelter-island/dering-harbor/
• Robins Island (Peconic Bay) — sold out from under them by Poggatacut to Nathaniel Sylvester (1651).
• Gardiner’s Island — their “Manchonat” (“the place where they all died,” per Tooker — a plague-emptied island), sold by Youghco and his wife Aswaw to Lion Gardiner in 1639. → ../../south-fork/communities/27-gardiners-island/

Overlay note: the Manhanset were the confederacy’s apex, so their story braids directly into the Corchaug of the North Fork (../corchaug/) and the Montaukett of the South Fork (../montaukett/) — Poggatacut’s grand-sachemship passed to Wyandanch on his death, and Manhanset survivors (and later the Corchaug sachem Ambusco) resettled among them.

History (contact, sachems, land deeds/transfers, dispossession)

• Deep antiquity. Occupation of Shelter Island runs back roughly 4,000 years; the historic Manhanset were seasonal fishers, clammers, hunters (deer, bear, wolf, raccoon) and gatherers (acorns, hickory, wild cherries, sumac, elderberries), per Muriel Porter Weaver, Where They Go By Water.
• The wampum economy. Peconic Bay was a prime source of quahog (Mercenaria) and whelk (Busycotypus) shell; as Pequot (and later Dutch/English) tributaries, the Manhanset produced wampum. This made the East End the “Mine of New Netherland.”
• Youghco / Poggatacut, grand sachem. On May 29, 1637 (three days after the English massacre of ~800 Pequots near Mystic), the Long Island sachems renounced Pequot tributary status; Wyandanch told Lion Gardiner he would consult “my brother… the great Sachem of all Long Island.” In 1639 Youghco and his wife Aswaw sold Manchonat (Gardiner’s Island) to Gardiner for ten coats of cloth. In 1644 Youghco led East End sachems to the United Colonies at Hartford to secure a protective “certificate” (which committed the English to little). He kept paying tribute (e.g., 60 fathoms of wampum to Gov. Winthrop, 1647) and juggling Dutch and English suitors; the Mohegan sachem Uncas accused him of witchcraft in 1649.
• The sale of Shelter Island (1637–1653). Earl of Stirling’s agent James Farrett claimed Shelter Island and Robins Island (c. 1637–38); he sold to Stephen Goodyear (1641), who on June 9, 1651 sold both islands to four Barbados sugar merchants — Thomas Middleton, Thomas Rouse, Constant Sylvester, and Nathaniel Sylvester — for 1,600 pounds of Muscovado sugar. Youghco fought the eviction (complaining via the Native interpreter Cockenoe to the United Colonies, Sept. 1652), but received payment Dec. 27, 1652; on March 23, 1653 he delivered “one turfe and twige” to Nathaniel Sylvester and John Booth and “with all his Indians… did freely and willingly depart the aforesaid island.” Numerous Manhansets joined the Montauk, Corchaug, and Shinnecock; others stayed on.
• Death of Poggatacut, 1653. The aged grand sachem died shortly after the transfer. Befitting his status, his body was carried from Shelter Island to Montauk for burial in the traditional upright, seated position; the funeral procession rested overnight south of Sag Harbor. Leadership of the confederacy passed to Wyandanch.
• Epidemic & the end of grand-sachemship. A major smallpox epidemic through 1664 killed ~two-thirds of the remaining Algonquian population. With Europeans now owning most East End land, they no longer needed a “Grand Sachem” to sign deeds; Gov. Nicolls decreed each group govern itself. Native people on Shelter Island lived on only by Nathaniel Sylvester’s courtesy — the colonial government noted Sylvester permitted the Corchaug sachem Ambusco and family to relocate there (c. 1675, during King Philip’s War).

Present-day descendants (honest status; avoid “last of the tribe” tropes)

Museum and chamber-of-commerce copy often implies the Manhanset simply vanished when Poggatacut “freely departed.” The archaeology and estate records say otherwise: Manhansets kept living and working on Shelter Island for at least a generation after 1653. Katherine Priddy’s peer-reviewed ethnohistory shows Giles Sylvester hired seventeen Manhansets (including a man whose name is recorded as “Sachem”) to reap wheat in 1682 at a pound per three-and-a-half days’ labor; Ambusco traded corn for apples in 1688; a Quaker visitor in 1659 noted “a great many Indians lived on it… Friendly and Sober… Serviceable to Friends for Guides.” They were a labor force in a Barbados-supply plantation economy alongside enslaved Africans (named in Sylvester wills: Tammero, Oyou, “Black John,” Tony, Nannie, and others) — a rare documented three-way colonial society of Native, African, and English people.

As a distinct polity the Manhanset do not survive; there is no recognized Manhanset nation today, and no reservation. Their descendants are best understood as absorbed into the Montaukett, Shinnecock, and Corchaug lineages — not “extinct.” The 19th-century “last of the tribe” framing is the same racial trope Strong debunks across all the Long Island peoples; apply the same caution here.

Sacred / archaeological sites

• Sylvester Manor, Shelter Island — the key site. The 1651 plantation sits on former Manhanset ground; it has been the subject of a major, long-running historical-archaeology project (University of Massachusetts Boston; the Northeast Historical Archaeology Sylvester Manor volume, 2007) documenting Native, African, and European co-residence. The Manor’s grounds include a known burying ground associated with enslaved and Native laborers. Today Sylvester Manor is an educational farm and museum — a living interpretive anchor.
• Mashomack Preserve vicinity / the “Smith site” — Roy Latham’s excavations recorded axes, celts, pestles, mortars, projectile points, pottery, hearths, and two house structures: “indications of an established settlement” (Porter Weaver). (Latham was an early-/mid-20th-century amateur collector; treat find-counts as indicative, not precise.)
• Sunset Rock — remembered in local tradition as the “throne” of Sachem Pogatticut; a visitable Shelter Island landmark.
• Manhanset Chapel, Shelter Island Heights — a 19th-century chapel named for the people (on the National Register; see NARA below), useful as a place-name survival rather than a Native site per se.
• Place-name survivals: Shelter Island itself retains “Manhanset” in businesses and districts; Mashomack, Menantic, Cobbetts Lane, and other hamlet/creek names are Algonquian.

NARA / federal records

State the gap honestly: The Manhanset have no reservation and no recognized successor nation, so there is no dedicated federal/BIA record series. The federal footprint on Shelter Island is the National Register of Historic Places / NPS program (which documents the colonial-era buildings on former Manhanset land, not the Manhanset as a people) plus incidental census maps. All naIds verified live against the National Archives Catalog API v2 (Nov 2026):

Note: searching “Manhanset Shelter Island” returns these NR records plus unrelated material (1940 census ED maps for Suffolk County, diplomatic despatches), confirming the gap. The real record is colonial and archaeological: Nathaniel & Grissell Sylvester’s wills (1680/1685, Sylvester Manor Archive at NYU); the United Colonies / New Haven records; Lion Gardiner’s memoir; Ralph Duvall, The History of Shelter Island (1932); Mallmann; and the UMass Boston Sylvester Manor excavations.

Why it matters to the corridor story

Shelter Island is the hinge of the East End — the land “sheltered by islands” between the two forks — and the Manhanset were, at contact, its political summit: Poggatacut spoke for all of Long Island. For Eastermost, the Manhanset supply the corridor’s most resonant single fact (a people whose name means “an island sheltered by islands,” on an island that is still exactly that) and its most honest hard history: Sylvester Manor is one of the best-documented sites in America for the braided colonial reality of Native dispossession and African enslavement in the same place. That complicates — in the right way — the Hamptons-and-yachts gloss the brand will otherwise meet east of here. Shelter Island reads as idyll; the Manhanset layer is what makes it deep.
