Seekonk is a town in Bristol County, Massachusetts, United States, on the Rhode Island border. It was incorporated in 1812 from the western half of Rehoboth. Until 1862, the town of Seekonk also included what is now the City of East Providence, Rhode Island. The land in the western half of the town was given to Rhode Island by the United States Supreme Court as part of a longstanding boundary dispute with Massachusetts. There have been many spellings of the name Seekonk. Some of the various spellings include Seconch, Sink Hunk, Secquncke, Seaconke, and Squannakonk. The symbol of the goose in flight is used on the Town Seal. The chief of the Wampanoags at the time the colonists settled in Southeastern Massachusetts was known as Massasoit or Ossamequin. In English this name means yellow feather. Ossamequin's people had been seriously affected by a plague just prior to the arrival of the Pilgrims at Plymouth. A large number of Wampanoag Indians had been killed by this illness. Most historians believe this plague to have been yellow fever.
