In 1912, Ernest Beaux married Iraïde de Schoenaich (1881–1961), who gave birth to their son, Edouard (1913–1993), the following year. During the Russian Civil War, Iraïde escaped from Russia through Finland with her infant son. They reached France by sea following a dangerous two-month-long voyage, during which time Iraïde fell deeply in love with another man. Ernest divorced her and took custody of their son, while Iraïde moved to Nice to work with her lover. Ernest later married Yvonne Girodon (1893–1980), with whom he had a daughter, Madeleine.
