Did Marie Antoinettes children survive the revolution?

Louis XVI and Marie-Antionette had two daughters and two sons. Two of these died before the Revolution. The two royal children alive during the Revolution were Louis the Dauphin, heir to the Throne, and Marie-Therese.

Marie-Therese and Louis were separated from their parents when they were imprisoned (both their parents were put on trial and executed). The Dauphin died in prison; it is not clear whether it was a deliberate murder or whether he simply died of illness in the unsanitary conditions of the prison. He was never put on trial.

Louis was later known as "Louis XVII" despite the fact that he was never crowned as King. A number of people attempted to impersonate him in later life and claim the French throne.

Marie-Therese survived the Revolution and died in 1851.
