Умберто II
In 1970, Mona was widowed again and, in 1971, married Bismarck's physician, "Count" Umberto de Martini, a nobleman (after Mona acquired a title for him from King Umberto II of Italy) who was 14 years younger than she. It was only after his death in a sports car accident in 1979 (later referenced by socialites as "Martini on the rocks") that Mona realized that Martini, like Bismarck, had married her for her money (exactly the same way she had married Schlesinger, Bush and Williams, so many years before). Martini turned out to be already married and had been secretly bilking Mona of funds for his children.
