In addition to his legitimate children, the Duke is said to have had a son by Kiki Preston (née Alice Gwynne, 1898–1946), an American socialite with whom he reportedly shared a "ménage à trois" with Jorge Ferrara, the bisexual son of the Argentine ambassador to the Court of St James's. Known as "the girl with the silver syringe", drug-addict Preston – a cousin of railroad heiress Gloria Vanderbilt – was married first to Horace R.B. Allen and then, in 1925, to banker Jerome Preston. She died after jumping out of a window of the Stanhope Hotel in New York City. According to the memoirs of a friend, Loelia, Duchess of Westminster, Prince George's brother (the Duke of Windsor) believed that the son was Michael Temple Canfield (1926–1969), the adopted son of American publisher Cass Canfield – and the first husband of Lee Radziwill, sister of Jacqueline Kennedy Onassis.
