François d'Orléans, Prince de Joinville was the third son of Louis Philippe, King of the French, and his wife Maria Amalia of Naples and Sicily. An admiral of the French Navy, François was famous for bringing the remains of Napoleon from Saint Helena to France, as well as a talented artist, with 35 known watercolours. He married Princess Francisca of Brazil, daughter of Emperor Pedro I and sister of Emperor Pedro II. The dowry received by François upon the marriage became the Brazilian city of Joinville.

Louis Philippe I, nicknamed the Citizen King, was King of the French from 1830 to 1848, and the penultimate monarch of France. As Louis Philippe, Duke of Chartres, he distinguished himself commanding troops during the Revolutionary Wars and was promoted to lieutenant general by the age of nineteen, but he broke with the Republic over its decision to execute King Louis XVI. He fled to Switzerland in 1793 after being connected with a plot to restore France's monarchy. His father Louis Philippe II, Duke of Orléans, fell under suspicion and was executed during the Reign of Terror.
