 And as for the one who started it all, Napoleon's brother Jerome, who married the beautiful American and couldn't take Huguemont at Waterloo, he went into exile after the battle, but returned to French politics after his nephew, Louis Napoleon, became emperor. He was made a Marshal of France and served as President of the French Senate. He died in 1860. His detainments, through Catherine of Württemberg, are the last remaining line of the Imperial House of Bonaparte.
