John Norton, 5th Baron Grantley

John Richard Brinsley Norton, 5th Baron Grantley, FSA, FRNS (1 October 1855 – 5 August 1943), was a British peer from an English landowning family. He became known also as an antiquary and a numismatist.

Early life
Norton was born in Florence, Italy, the son of Thomas Norton, 4th Baron Grantley and his wife, Maria, née Federigo, and a grandson of Caroline Norton, the writer. He was educated at Highgate School from 1867 until 1869, and then at Harrow School and the University of Dresden. He inherited his father's title in 1877 and was at some time a captain in the Middlesex Yeomanry.

Estates
Grantley was a Fellow of the Society of Antiquaries of London, the Royal Numismatic Society and the British Numismatic Society. His country seats were Weeke Manor in Winchester and Markenfield Hall in Ripon. He also owned Elton Manor in Nottinghamshire for a time, but seems hardly to have lived there. He purchased the Red Rice estate in 1913.

In 1879, Grantley married Katharine Buckner Norton, née McVickar (died 1897), the former wife of his cousin, Charles Grantley Campbell Norton. She was the daughter of Commodore William Henry McVickar, US Navy, of New York. They had six children.
