But after annual visits over the next decade, her parents decided to repatriate their family to Petropolis permanently, where Isabelle attended day school at Notre-Dame-de-Sion while the family took up residence at the old imperial Grão Pará Palace. Until then, Isabelle was privately educated by governesses and tutors. Marriage Princess Isabelle first met her third cousin, Prince Henri of Orléans, heir to the Head of the House of Orléans, in 1920 at the home of the Duchess of Chartres, Henri's grandmother who was also a cousin of both of Isabelle's grandparents. In the summer of 1923, Henri was a guest at the Chateau d'Eu, at which time Isabelle, aged 12, resolved that she would one day marry him.
