Hadley, most famous as the name of Ernest Hemingway's first wife, is more sophisticated, professional, and modern than cousins Harley, Haley, or Hayden. The hit book The Paris Wife, a novel by Paula McLain told from the point of view of Hadley Hemingway (born Elizabeth Hadley Richardson), has helped popularize the name, which also appears on the vampire show True Blood. Hadley could become this generation's Hailey. Adley, a mashup of Hadley and Addie, has also appeared on the scene.
