Princess Maria Antónia of Bragança

Princess Maria Antónia of Braganza,  (Maria Antónia Micaela Rafaela Gabriela Adelaide Xavier Josefa Expedita Gregoria) (12 March 1903, Viareggio, Lucca, Toscana, Italy – 6 February 1973, Water Mill, Suffolk, New York) was a member of the House of Braganca. She married Sidney Ashley Chanler, the grandson of John Winthrop Chanler and Margaret Astor Ward.

Family
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.

Marriage and issue
Maria Antónia married American heir Sidney Ashley Chanler (1907–1994) on June 13, 1934, at Burg Seebenstein. Chanler was the son of novelist, politician, and explorer Rep. William A. Chanler and stage actress Minnie Ashley, thus making him a relative of the Stuyvesant family, the Astor family, the Livingston family, the Schuyler family, and the Dudley-Winthrop family, as well as a descendant of John Jacob Astor, Samuel Ward, Jr., Gen. John Armstrong, Gov. William Greene, Gov. William Greene Jr., Samuel Gorton, Robert Livingston, Gov. Richard Ward, Peter Stuyvesant, and others. They later divorced in December 1948. She never remarried, though he remarried twice.

During her marriage, Maria Antónia used the title and style of: Her Royal Highness Princess Maria Antónia of Braganza, Mrs. Chanler.
