Sykes Rellie's grandfather, Christopher Sykes (1907–1986), whom she knew as "Fat Grandpa" or "F.G.", was a friend and official biographer (1975) of the novelist Evelyn Waugh and son of the diplomat Sir Mark Sykes, sixth baronet (1869–1919), associated with the so-called Sykes-Picot Agreement of 1916, by which Britain and France provided for the partition of the Ottoman Empire after the end of the First World War.
