Maria Letizia Bonaparte

Umberto I (Italian: Umberto Rainerio Carlo Emanuele Giovanni Maria Ferdinando Eugenio di Savoia; 14 March 1844 – 29 July 1900), nicknamed the Good (Italian: il Buono), was the King of Italy from 9 January 1878 until his assassination on 29 July 1900.

Napoléon Bonaparte (15 August 1769 – 5 May 1821) was a French military and political leader. He rose to prominence during the French Revolution and led several successful campaigns during the Revolutionary Wars. As Napoleon I, he was Emperor of the French from 1804 until 1814, and again in 1815. Napoleon dominated European and global affairs for more than a decade while leading France against a series of coalitions in the Napoleonic Wars. He won most of these wars and the vast majority of his battles, building a large empire that ruled over continental Europe before its final collapse in 1815. One of the greatest commanders in history, his wars and campaigns are studied at military schools worldwide. He also remains one of the most celebrated and controversial political figures in history.

Napoléon Joseph Charles Paul Bonaparte (9 September 1822 – 17 March 1891), usually called Napoléon-Jérôme Bonaparte or Jérôme Bonaparte, was the second son of Jerome, King of Westphalia, youngest brother of Napoleon I, and his second wife Catharina of Württemberg. An outspoken liberal, he became the de facto head of the House of Bonaparte from 1879 to his death. He was not considered a legitimate pretender to the throne by many Bonapartists, due to his father's previous marriage without divorce. They instead preferred his son Victor. From the 1880s he was one of the stronger supporters of General Georges Boulanger, together with other monarchist forces.

Maria Clotilde of Savoy (Ludovica Teresa Maria Clotilde; 2 March 1843 – 25 June 1911) was born in Turin to Vittorio Emanuele II, later King of Italy and his first wife Adelaide of Austria. She was the wife of Napoléon Joseph Charles Paul Bonaparte.
