Archduchess Maria Antonia was nineteen years old at the fall of the Habsburg monarchy. The end of World War I marked a sharp down turned in her family's prosperity. The
republican government of Austria confiscated the properties of the Habsburgs. The family lost all their fortune. Maria Antonia's eldest brothers, Archdukes Rainer and Leopold, remained in Austria and they recognized the new republic. The rest of the family moved to Spain in January 1919. They settled in Barcelona living with simplicity with very limited means. While Maria Antonia's three elder sisters Archduchess Dolores, Inmaculata and Margareta were pliable, Archduchesses Maria Antonia and her younger sister Assunta were more rebellious and clashed often with their mother, Infanta Blanca. While living in Barcelona Maria Antonia turned increasingly towards religion. Although both of her parents were observant Catholics, they found Maria Antonia's religious fervor worrisome particularly because her sister Assunta followed Maria Antonia's lead. Archduchess Maria Antonia wished to become a nun, but her mother thought that Maria Antonia had neither the necessary vocation nor the temperament to follow a religious life. To make her reflect on her decision Maria Antonia's parents took her to the Island of
Mallorca. At the same time Infanta Blanca and her husband wanted to see if there were any properties they could claim from Archduke Ludwig Salvador's uncle who had died a decade earlier, unmarried. The family found that there was nothing left they could have inherited. Archduchess Maria Antonia quickly left behind her intentions to become a nun. She fell in love with Ramon Orlandis y Villalonga (1896–1936), who belonged to the minor Spanish nobility, but like the Archduchess, he lacked personal fortune. His father had lost his title when he failed to pay the taxes of nobility. The marriage took place in Barcelona on 16 July 1924. The couple lived in Mallorca where they were the parents of five children who bore the surname Orlandis y Habsburgo: • Blanca Maria (1926–1969) married in 1948 Raul Ereñu (1908–1969). They had five children • Juan,
Baron de Pinopar (1928–1977) married in 1951 Hildegarde Bragagnolo (1932–2001). They had eight children. • Maria Antonia (1929–1991). Died unmarried • Isabel (1931) married in 1954 Fausto Morell, Marqués de Sollerich (1926–2003). They had six children. • Alfonsina (1936) married in 1981 Joaquín Zaforteza (born 1930). They had no issue. Archduchess Maria Antonia's husband died during the
Spanish Civil War in 1936. A widow with five children Archduchess Maria Antonia, as the widow de Orlandis, emigrated to South America. In 1942, in
Uruguay, she married Argentine-born Don Luis Perez Sucre (1899–1950). Her second husband died eight years later. Archduchess Maria Antonia died in
Brazil in 1977. ==Ancestry==
