Maria Antónia was born at the Villa Arciducale in Viareggio, a Tuscan commune. Her namesake, the Duchess of Parma, was sister-in-law to the Villa's owner, Infanta Bianca of Spain, Archduchess of Austria. This hospitality was likely why Maria Antónia was named after her father's sister. Her parents, Miguel Januário, Duke of Braganza, and Princess Maria Theresa of Löwenstein, were the Miguelist claimants to the deposed Portuguese throne. Maria Antónia was thus an aunt to Johannes, 11th Prince of Thurn and Taxis and Duarte Pio, Duke of Braganza, as well as a first cousin, twice removed to Hans-Adam II, Prince of Liechtenstein, King Albert II of Belgium and Henri, Grand Duke of Luxembourg.
