Wie trouwde met Pedro Caldeira Brant, 1st Conde de Iguassú?

Maria Isabel de Alcântara Bourbon (28 February 1830 – 5 September 1896) was the third daughter (fifth child) of Emperor Pedro I of Brazil and his mistress, Domitila de Castro, Marchioness of Santos.

Maria Isabel received the same name as her second sister, the Duchess of Ceará, who died in 1828 at only two months old. Her father never gave her any titles due to his marriage to Amélie of Leuchtenberg. Still, Pedro I acknowledged her as his daughter in his will but gave her no share of his state, except asking for his widow to aid in her education and upbringing. He wished she was given a good European education like her oldest sister, the Duchess of Goiás. However, the Marchioness declined to send the girl to Europe.
