He was a member of a junior branch of an ancient Northumbrian family and was distantly related to William, Lord Widdrington. He was a younger brother of Sir Thomas Widdrington and Henry Widdrington.
He was educated at Christ's College, Cambridge, [1] where he made the acquaintance of John Milton. In 1654, he was appointed Regius Professor of Greek and in 1673, Lady Margaret's Professor of Divinity. [2]
