The Accominta people, also known as Agamenticus, were a small tribe or band of the Pennacook Confederacy. They first occupied a village of the same name at or near the site of present-day York, Maine, to which the name “Boston” was given on some early maps. English explorer, Captain John Smith said that they were allied with other tribes immediately north of them, and were subject to attacks by the Penobscot, which would seem to place them in the Abenaki Confederacy, though later they were correctly included in the Pennacook Confederacy. Under what name the Accominta people were subsequently recognized is not known.
In the Jesuit Relations of 1640, their location was given on the north shore of Lake Huron, at the mouth of the French River. The Amikwa are mentioned in the same connection as residing on this stream. In the Jesuit Relations of 1658, they appear to have been living farther north on the river that they trailed with the Cree. In the Jesuit Relations of 1670 they were said to have been attached to the mission of Sault Ste Marie, but, only went there to fish.
