Lumley was one of the
Immortal Seven, the English noblemen who invited
William of Orange to invade England and depose his father-in-law,
James II. He secured
Newcastle for William in December 1688. After William became King, he appointed Lumley in rapid succession in 1689/90 as a
Gentleman of the Bedchamber, a member of the
Privy Council, Colonel of the
1st Troop of Horse Guards (until 1699),
Viscount Lumley of Lumley Castle,
Lord Lieutenant of Northumberland and
Lord Lieutenant of Durham. Lumley was created
Earl of Scarbrough on 15 April 1690. Scarbrough took part in the
Battle of the Boyne in 1690 and was afterwards in
Flanders. He was appointed major-general in May 1692 and lieutenant-general on 4 October 1694, retiring from active service after the
Treaty of Ryswick in 1697 (though he received a new commission as lieutenant-general of all the forces on 9 March 1701/2). He was
Chancellor of the Duchy of Lancaster from 1716 to 1717. After his elevation, he significantly extended his family seat at
Lumley Castle. He died of apoplexy in Gerard Street,
Soho, on 17 December 1721. ==Family==
