Born in Bologna, Italy, he is the youngest son of Massimo Cordero dei Marchesi di Montezemolo (1920–2009), a Piedmontese aristocrat whose family served the Royal House of Savoy for generations, and Clotilde Neri (b. 1922), niece of famed Italian surgeon Vincenzo Neri. His uncle, Admiral Giorgio Cordero dei Marchesi di Montezemolo (1918–1986) was a commander in the Regia Marina in World War II. His grandfather, Mario (1888–1960) and great-grandfather Carlo (1858–1943) were both Generals in the Italian Army. He is also a relation to Andrea Cordero Lanza di Montezemolo (his father Massimo and Andrea were cousins), who became a cardinal in 2006 and whose father, colonel Giuseppe Cordero di Montezemolo, was killed by the Nazi occupation troops during the massacre of the Fosse Ardeatine in Rome in 1944. His surname is actually "Cordero di Montezemolo" and the correct usage is either the full surname or just Montezemolo (omitting the "di"); Marchesi is a noble title.
