Chappaquidick Wampanoag Tribe"The Chappaquiddick Wampanoag Tribe is a historical Massachusetts tribe. Its ancestral homelands are Chappaquiddick Island, Cape Poge, and Muskeget. The Chappaquiddick Wampanoag were a tribe at the time of first contact, when the United States became a country in 1776, and when Massachusetts became part of the Federal Union in 1789. The tribe had two reservation areas on Chappaquiddick until the late 1800s. Today, Chappaquiddicks live in Martha’s Vineyard, the larger island next to Chappaquiddick, on the mainland in Massachusetts and Rhode Island (ancestral homelands of the Wampanoag Nation), and throughout the United States.
