Mattabeseck

Mattabesset was a region and settlement once occupied by Algonquian language-speaking Native Americans called the Wangunk, along the Connecticut River. The Mattabesset River reaches the Connecticut River near Middletown, Connecticut. The settlement of Mattabesset became Middletown, on the east bank of the Connecticut, and a succession of settlements on the west, including Chatham and Middle Haddam which today is East Hampton, Connecticut.

Spellings on the name vary widely and include Mattabesec, Mattabeseck, Mattabesic, Mattabesset, and Mattabéeset.

This region was occupied by a tribe known as the Wangunks. Dutch explorers initially visited the region in 1614. At the time of English settlement of the area, the local sachem, or Native political leader, was Sowheag, also known as Sequin. After conflict with settlers, he moved from the village of Pyquaug, or Weathersfield, Connecticut, to Mattabesett.

As recorded by historian John Warner Barber:

"The lands in this township were obtained from the Indians in connection with the lands in Middletown. But a reservation, laid out partly at Indian hill, and partly a little east of the Chatham meeting house, was held by them till about 1767; when, having dwindled to small number, they sold their, and united with the Farmington Indians. These Indians have been sometimes called Wongonks or Wongoms, but the reservation was for the heirs of the Sowheag and Mattabessett Indians, and they were doubtless of the same tribe with the Indians on the weest side of the river. A little clan inhabited, or frequented, the region about Pocotopogue pond, and had a place of rendezvous on the principal island which that encloses. These were also, probably, a part of the Mattabessett Indians."

In 1650, the General Court of Connecticut sent researchers to the Mattabesett region and believed Middletown and Chatham could support 15 families. Sowheag apparently had ceded some of the land to Governor John Haynes.
