  General Notes:

Louis-Joseph-Xavier-François (October 22, 1781-June 4, 1789) was the second child and first son of King Louis XVI of France and Queen Marie Antoinette. As the heir apparent to the French throne, he was called the dauphin. A sweet-natured child, unlike Madame Royale, Louis-Joseph died at the age of seven of what was then known as "consumption" (tuberculosis). On his death the title of dauphin passed to his younger brother Louis-Charles (1785-1795), who would survive his father and die in prison at the age of ten. ¹⁵⁷⁴
