Grand Duchess consort and regent of Luxembourg (1861-1942)

Infanta Marie Anne of Portugal (Portuguese: Maria Ana de Portugal; born Maria Ana do Carmo Henrique Teresa Adelaide Joana Carolina Inês Sofia Eulália Leopoldina Isabel Bernardina Micaela Gabriela Rafaela Francisca de Assis e de Paula Inácia Gonzaga; 13 July 1861 – 31 July 1942) was Grand Duchess of Luxembourg as the wife of Grand Duke William IV. She was the regent of Luxembourg between 1908 and 1912; first during the illness of her spouse, and then in the name of their daughter, Grand Duchess Marie-Adélaïde.
Family
Born at Schloss Bronnbach in Bronnbach, Kingdom of Württemberg, Infanta Marie Anne (or Maria Ana) was the fifth child and second-youngest daughter of the deposed King Miguel of Portugal and his wife Princess Adelaide of Löwenstein. She was a member of the House of Braganza. At the time of her birth, her father had been exiled, and the family lived as guests in the Austro-Hungarian Empire.
In spite of their circumstances, the daughters of Princess Adélaïde and Miguel made royal marriages, some to reigning monarchs and deposed heads of Roman Catholic European dynasties.
Marriage and children
Before her marriage with William IV, Grand Duke of Luxembourg, she was considered by Emperor Franz Joseph I of Austria as a suitable bride to his only son, Crown Prince Rudolf, but Rudolf did not like her, and she remained single for the next years.
Maria Ana was married on 21 June 1893 at Schloss Fischhorn, Zell am See, to the Protestant Wilhelm, Hereditary Grand Duke of Luxembourg, the son and heir apparent of Adolf, Grand Duke of Luxembourg, head of the House of Nassau. It was agreed that the children would be raised in their mother's Catholic faith, the religion of the overwhelming majority of Luxembourg's population.
The couple had six daughters:
Marie-Adélaïde, Grand Duchess of Luxembourg (1894–1924), who remained unmarried and childless
Charlotte, Grand Duchess of Luxembourg (1896–1985), who married her first cousin Prince Felix of Bourbon-Parma, a son of Marie Anne's younger sister.
