In 1648, Ichabod was received in Portsmouth as freeman, and was on a committee for the "tryall of the General Officers". At various times, he served as constable, deputy to the General Assembly, on several town committees, and elected to the town council. His land lay in the central part of Portsmouth. In 1681 he purchased land on the west side of the Taunton River. This tract was located in what is now the town of Dighton, MA. Late in his life he appears to have removed to the home of his son Major Nathaniel Sheffield, in Newport, where he died. He is buried beside his son, Nathaniel, in the Clifton Burying Ground in that town. (from G. Andrew Moriarty, One Branch of the Rhode Island Sheffields, in Colonial Rhode Island Vol. 2)
