Meaning and history
Medieval English form of Hilarius or Hilaria, Hilary was mainly a masculine name in the Middle Ages but was revived in Britain in the early 20th century as a predominantly feminine name. In the United States, both Hilary and the variant Hillary declined in popularity after Hillary Clinton (1947-) became first lady in 1993. Notable bearers include the American actresses Hilary Swank (1974-) and Hilary Duff (1987-).
