Kurš apprecējās ar Princess Francisca of Brazil?

Dona Francisca (2 August 1824 – 27 March 1898) was a princess of the Empire of Brazil (as daughter of Emperor Dom Pedro I, who also reigned as King Dom Pedro IV of Portugal, and his first wife Maria Leopoldina of Habsburg), who became Princess of Joinville upon marrying François d’Orléans, son of the French king Louis Philippe I. The couple had three children. Through their oldest daughter, Francisca and François are the ancestors of Jean, Count of Paris, the present Orléanist pretender to the French throne.

François d'Orléans, Prince de Joinville (14 August 1818 – 16 June 1900) 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.

François and Francisca's grandson Jean went on to become the Orléanist claimant to the extinct French throne, a claim passed on to his son, grandson and now great-grandson Jean, Count of Paris, current Orléanist claimant to the French crown.
