Hélie de Talleyrand-Périgord (1859–1937), duke of Talleyrand, prince, then duke of Sagan, was a French socialite and son of Boson de Talleyrand-Périgord.
Talleyrand was born in 1859 and married Anna Gould in 1908. Anna was previously married (1895-1906) to his cousin, Comte Boni de Castellane, later Marquis de Castellane. They had the following children:
Howard de Talleyrand (1909–1929) duc de Sagan, who took his own life on May 28, 1929 at his parent's home in Paris when told he could not marry. He was taken to a hospital on Rue Puccini, where he died. His parents thought at age not yet 20, he was too young to marry. Hélie and Anna said: "... we had no objection to the girl, but only opposed the marriage because of our son's age."
Helene Violette de Talleyrand (1915–2003) who married James Robert de Pourtales on March 29, 1937 in Val Saint-Germain, she then divorced in 1969 (their son Hélie married as her second husband, the eldest daughter of Marie Clotilde Bonaparte), and married Gaston Palewski (1901–1984), the Minister of Scientific Research and Atomic and Space Questions from 1962 to 1966. They married on March 20, 1969 in Paris.
Talleyrand died in 1937 of a heart attack in Paris.
