an English Roman Catholic martyr and saint.
He was born at Rodsley, Derbyshire, and was educated at Eton College. In 1568, he was nominated by Sir William Petre to one of the eight fellowships which he had founded at Exeter College, Oxford, probably influenced by Sherwin's uncle, John Woodward, who from 1556 to 1566 had been rector of Ingatestone, Essex, where Petre lived. A talented classical scholar, Sherwin graduated Master of Arts on 2 July 1574, and the following year converted to Roman Catholicism and fled abroad to the English College at Douai, where he was ordained a priest by the Bishop of Cambrai on 23 March 1577. On 2 August 1577, he left for Rome, where he stayed at the English College, Rome for nearly three years
