[2] He was the son of Richard Sturgis Seymour and Lady Victoria Alexandrina Mabel FitzRoy.
His diplomat father had been posted to La Paz in Bolivia and George's mother went too.
After his uncle's death in 1949, with heavy death-duties Seymour was compelled to buy the house he had expected to inherit and, in a country auction, as many of its contents as he could afford.
He borrowed £50,000, (equivalent to £2,231,331 as of 2023) [4] and by selling the majority of the estate, paid it back within the year.
He is posthumously the subject of the book Thrumpton Hall: A Memoir of Life in My Father’s House written by his daughter, Miranda Seymour.
