Charlotte Marie Pomeline Casiraghi (born 3 August 1986) is the second child of Caroline, Princess of Hanover, and Stefano Casiraghi, an Italian industrialist. She is ninth in line to the throne of Monaco. Her maternal grandparents were Rainier III, Prince of Monaco, and American actress Grace Kelly. She is named after her maternal great-grandmother, Princess Charlotte, Duchess of Valentinois. She was christened on 20 September 1986. Her godparents are Albina du Boisrouvray and Stefano Casiraghi's brother-in-law, Massimo Bianchi.
Charlotte and her two brothers, Andrea and Pierre, were born in the Mediterranean Principality of Monaco, ruled by their maternal grandfather, Prince Rainier III. When she was four years old, her father was killed in a boating accident. After his death, Princess Caroline moved the family to the Midi village of Saint-Rémy-de-Provence in France, with the intention of minimising their exposure to the press.
