Wanton was a merchant, and like his father was a
Quaker, and the Friends' records state that "for many years he was a valuable public friend." He first entered public service in 1706 as a deputy from Newport serving for several years in that capacity, and also as the
Speaker of the House of Deputies. He was called Colonel John Wanton in 1706 when he went after French
privateers with John Dublin, who was wounded in the action. Between 1721 and 1734 Wanton was the Deputy Governor for the colony, and following the death of his brother,
William Wanton, he became governor in 1734, serving continuously until his own death in 1740. He was buried in the
Coddington Cemetery in Newport. ==Personal life==
