No, Mariel. The Hereditary Grand Duke of Luxembourg is a member of the House of Bourbon-Parma, but his great-great-grandmother was a Infanta Maria Ana of Portugal, a member of the House of Braganza (ancestor House of the Orleans-Braganzas), who became Grand Duchess of Luxembourg.
Grand Duchess Maria Ana was daughter of King Miguel of Portugal. The Imperial Family of Brazil (House of Orleans-Braganza) descends of Emperor Pedro I (King Pedro IV of Portugal), brother of King Miguel.
But Hereditary Grand Duke Guillaume of Luxembourg is a second cousin of Prince Rafael of Brazil, because their share the late Grand Duchess Charlotte of Luxembourg as great-grandmother.
Now, I made me think about that Prince Rafael and his sisters, Princesses Amélia and Maria Gabriela can have twin children, because this genetical "trait" runs in the House of Orleans-Braganza and in the House of Bourbon-Parma.
Not only Prince Jean of Luxembourg and Princess Margaretha of Liechtenstein are twins, their brother, Prince Guillaume, is father of twins, Prince Léopold and Princess Charlotte of Nassau.
