James Henri Le Bailly de la Falaise was born on February 11, 1898, in
Saint-Cyr-l'École, France, the eldest son and second child of Louis Venant Gabriel Le Bailly de la Falaise, écuyer (1866–1910), a three time
Olympic gold-medallist in fencing and former Army officer. His mother was the former Henriette Lucie Frédérique Hennessy (1873–1965), scion of the Cognac family. After his father died in 1910, his widowed mother married her second husband, Count Antoine Hocquart de Turtot (1872–1954), a cavalry officer and major French horse-racing figure, in 1912. His mother and father had four children together: • Louise Le Bailly de La Falaise (1894–1910) • Henri James Le Bailly de La Falaise, Écuyer (1898–1972), film director and producer, war hero and translator. • Alain Le Bailly de La Falaise, Écuyer (1905–1977). His mother had another child with her second husband, de La Falaise's half-sibling • Henriette-Hyacinthe-Olympe-Geneviève Hocquart de Turtot (born c. 1913).
Title The title held by the head of the family, Marquis de La Coudraye, dating from 1707, was granted, by an 1876 act of succession, to the younger son of Pacôme-François Le Bailly, Seigneur de La Falaise, and his wife, Pauline-Louise-Victoire de Loynes, daughter of the Marquis de La Coudraye. La Falaise inherited the title of Marquis de La Coudraye from his paternal grandfather, Gabriel-César-Henri Le Bailly de La Falaise, who, like his father, died in 1910 (the father died on April 4, the grandfather on August 6). Since La Falaise had no children, the title of Marquis de La Coudraye was inherited by his younger brother, Alain de La Falaise (died 1977). It then passed to his nephew, Alexis de La Falaise (died 2004). It is now held by his grand-nephew (grandson of Alain), Daniel de La Falaise, a professional chef and food writer.
Name His actual surname was
Le Bailly, though he and other members of his family used
Le Bailly de la Falaise, referring to an ancestral estate; it is typically abbreviated to
de la Falaise. As the marquis told
The New York Times (October 7, 1925), "My patronymic name is Le Bailly, but ... I use the name de la Falaise because it is one of the great-grandfather branches of the Le Bailly family. De La Falaise is the only existing branch of that family today. So this should be my entire name: James Henry Le Bailly de La Falaise, Marquis de La Coudraye". ==Military service==
