I'm searching for his place of burial, and the likeliest place would seem to be at Weston-sub-Edge; if not there, then possibly Scarborough, North Yorkshire.
Major de Freville and his wife, Margaret, lived at Weston-sub-Edge, Gloucestershire, but he also had connections with Cambridgeshire and Essex, and despite obituaries appearing in several regional newspapers, there was no mention of where he had been interred.
He'd been invalided home from the war in South Africa in October 1900, having contracted enteric fever. By late 1901 his health was so poor that he retired to Scarborough "with which place his wife's family are connected," and died there on Saturday 12th October 1901.
Born Edward Henry Greene, he changed his name to Edward Henry Greene de Freville by Royal license in 1885, when he succeeded to the Cambridgeshire estates of his aunt.
Mrs de Freville's maiden name was Rickaby, and she was connected with the Boynton family of Burton Agnes, East Yorkshire. She died at Maugersbury, Stow-on-the-Wold on 22nd August 1939, and was buried at St Lawrence's Church, Weston-sub-Edge.
