Originally a French feminine diminutive form of Jacques, the French version of James. In the 1960s it became very popular in the United States and elsewhere, influenced in part by the fame and stylish image of Jacqueline Bouvier Kennedy Onassis (1929–94), whose family was of French extraction.
French: from the personal name Privat, Latin Privatus (from privatus ‘private citizen’, i.e. not a public official). This was the name of several early saints, including a bishop of Mende, martyred in the 3rd century.
