The Earl of Carnarvon was the only son of the 6th Earl of Carnarvon by his first (American-born) wife Catherine Wendell. Like his father, Carnarvon (then known as Lord Porchester) also fell in love with an Anglo-American, Jean Margaret Wallop of Big Horn, Sheridan County, Wyoming.
He served as a Lieutenant in the Royal Horse Guards, later becoming Honorary Colonel of the 116th (Hampshire Fortress) Engineer Regiment (Territorial Army). The Queen called Lord Carnarvon "Porchy," after the courtesy title he used before succeeding to the earldom of Carnarvon upon the death of his father, the sixth earl. After his death, John Warren succeeded his father-in-law as the Queen's racing manager.
He was also the Chairman of the South East Economic Planning Council.
He died aged 77 in 2001.
The Wallop family were also members of the English nobility not far from the Earls of Carnarvon. Carnarvon was an independent member of the Hampshire County Council (though he later took the Tory whip) and became its Chairman.
