Edward Radclyffe, eldest son of the wealthy landowner, Sir Francis Radclyffe was instrumental to his father’s plans for social advancement at the court of James II. His marriage to the 14 year old Mary Tudor was encouraged by James II, who, only a few months after the wedding in March 1688, created the groom’s father Viscount Radclyffe and earl of Derwentwater, whereupon Edward adopted the courtesy title of Viscount Radclyffe.
In June 1688 Radclyffe and his younger brothers were all appointed deputy-lieutenants of Northumberland. His brothers also served as officers in northern regiments of the royal army during the autumn of 1688 and Edward too, though still in London in October, was commissioned to raise troops in Yorkshire and Durham, where the Dutch invasion was expected to take place. In late November he was given a pass to attend the king at his camp in Salisbury.
During the reign of William III, when his Catholicism and refusal to swear the oaths excluded him from the House, he remained in London at his house in Arlington Street and seldom visited the ancestral home in Dilston. He had ambitions to be a poet and the Catholic, John Dryden, saw him as a possible patron. Dryden dedicated his Examen Poeticum (1693) to him, although he was later to admit to a friend, that as a poet Derwentwater was ‘none of the best’.
He remained firm in his faith and allegiance, and in an analysis of the attitudes of the peers to the succession, drawn up sometime in early 1705, Derwentwater was marked as a Roman Catholic and Jacobite. He died shortly after this list was made, in April 1705. At his death his titles passed to his eldest son James, then in France where he was being raised as the companion of the ‘Old Pretender’.
