Marie-Thérèse Charlotte of France (19 December 1778 – 19 October 1851), Madame Royale, was the eldest child of Louis XVI and Marie Antoinette, and the only one to reach adulthood (her siblings all dying before the age of 11). She was married to Louis Antoine, Duke of Angoulême, who was the eldest son of the future Charles X, her father's younger brother; thus the bride and groom were also first cousins.
