Family.
Yolande was born in Madrid as the second daughter of Eugène, 11th Prince de Ligne and his wife Philippine de Noailles (1898-1991). Her father was the Belgian ambassador to India from 1947 to 1951, ambassador to Spain from 1951 to 1958, and the head of one of Belgium's historically most influential noble families. He died in 1960.
Each of Yolande's two brothers became the Prince de Ligne (Baudouin, 12th Prince de Ligne and Antoine, 13th Prince de Ligne). Antoine is the father of Michel, 14th Prince de Ligne and Princess Christine, wife of Prince Antônio of Orléans-Braganza (second-in-line to the defunct Brazilian throne). Antoine's youngest daughter is named after Yolande.
Biography.
Marriage and issue.
On 17 January 1950 at the Château de Beloeil, Belgium (the family seat of the House of Ligne), Yolande married Archduke Carl Ludwig of Austria (1918–2007). The fifth child of Austria's last emperor, Charles I and his wife Zita of Bourbon-Parma, Carl Ludwig and Yolande were childhood sweethearts. Wedding guests included Carl Ludwig's eldest brother Crown Prince Otto (claimant to the Habsburg throne) as well as members of half a dozen other royal families; representatives of the Belgian royal family did not, however, attend. The couple honeymooned in Florida, eventually settling in New York City, where Carl Ludwig worked for the Rockefeller Foundation.
They had four children:
