A dark mystery shrouds the fate of the eldest son of Louis XVI of France and Marie Antoinette, who was eight years of age at the time his father was murdered by the Jacobins. After the downfall of Robespierre and his fellows, it was declared that the prince died in prison in 1795, while the royalists believed he had been secretly hidden away in the United States. Curious facts and circumstances pointed to Rev. Eleazar Williams, a reputed half-breed Indian, of the Caughanawaga tribe, near Montreal, as the surviving prince, who, for almost sixty years, had been hidden from the world in that disguise.
