Wie trouwde met Prince Luís of Orléans-Braganza (1878–1920)?

Prince Luís of Orléans-Braganza (26 January 1878 – 26 March 1920), nicknamed "the Perfect Prince", was the second son of Isabel, Princess Imperial of Brazil and Prince Gaston, Count of Eu, and patriarch of the Vassouras branch of the House of Orléans-Braganza. His maternal grandfather, Pedro II of Brazil, was the last emperor of Brazil. After being declared successor to the title of Head of the Imperial House of Brazil by his brother Pedro de Alcântara, Prince of Grão-Pará, following the latter's abdication to get married, Luiz ended up dying before his mother, Isabel, in 1920.

He was exiled along with his family as the result of the 1889 coup d'état that resulted in the formation of the republic. In 1908, the year he married, his older brother Pedro renounced his claim to succeed his mother in her claim to the imperial throne, leaving Dom Luís as her heir. In this role, he worked with monarchists in Brazil in several attempts to restore the monarchy. At the outbreak of World War I, he enlisted as an officer with the British Armed Forces and saw action in Flanders where he contracted a virulent form of rheumatism that caused his death at the age of 42. His efforts on behalf of the Allies of World War I saw him decorated by Belgium, France and Great Britain.
