Princess Maria Pia of Savoy 

Princess Maria Pia of Bourbon-Parma (née Princess Maria Pia of Savoy; born 24 September 1934) is the eldest daughter of Umberto II of Italy and Marie-José of Belgium. She is the older sister of Princess Maria Gabriella of Savoy, the Prince of Naples, and Princess Maria Beatrice of Savoy.
Maria Pia Elena Elisabetta Margherita Milena Mafalda Ludovica Tecla Gennara di Savoia was the second-born child of the Prince and Princess of Piedmont, born in Naples, Italy in 1934. Her parents, married since 1930, were unhappy together, as her mother confessed in an interview many years later (On n'a jamais été heureux, "We were never happy"), and separated after the Italian monarchy was abolished by plebiscite on 2 June 1946. Exiled, the family gathered briefly in Portugal, and she and her three younger siblings soon went with their mother to Switzerland while their father remained in Portugal. Being devout Catholics, her parents never divorced. On the royal cruise of the yacht, Agamemnon, hosted by Queen Frederika of Greece on 22 August 1954, she met and later married Prince Alexander of Yugoslavia (born 1924), son of Prince Paul of Yugoslavia and Princess Olga of Greece and Denmark. Not long after their wedding, Maria Pia gave birth to the couple's set of fraternal twin sons. Another set of twins was born to Maria Pia during the marriage five years later. The couple were divorced in 1967. In 2003 she remarried to Prince Michel of Bourbon-Parma (born 1926), son of Prince René of Bourbon-Parma and Princess Margaret of Denmark, and divorced from Princess Yolande de Broglie-Revel, by whom he has five dynastic children, and who is also the father of a child born out-of-wedlock in 1977, Amélie de Bourbon de Parme. Through him she is a sister-in-law of Queen Anne of Romania. Her ex-husband, Prince Alexander, also re-married to Princess Barbara of Liechtenstein, a cousin of that principality's monarch, and they have one son, Prince Dushan.
