Stapleton was the grandson of Sir William Stapleton, who followed Charles II into exile in France, and after the Restoration was appointed deputy-governor of Montserrat and captain-general of the Leeward Islands, with a baronetcy.
Our knighthood of the shire went a begging ... One Sir William Stapleton, a West Indian, formerly of Christ Church, a rake then as I hear he is still, is to be [the] man. He has but little estate in Oxfordshire, and that by his wife Mrs. Paul.
HMC Portland, vii. 450.
Returned unopposed, he voted against the Administration in every recorded division. His only recorded speech was made on the resolutions for a bill for the relief of the sugar colonies, 21 Feb. 1733, when he successfully opposed the importation of rum from the North American colonies into Ireland as detrimental to the sugar colonies. He was the only unofficial member of the committee appointed to draft the bill, known as the Molasses Act.
He died at Bath 12 Jan. 1740.
