Famous bearers include the American actresses Jennifer Aniston (1969-), Jennifer Garner (1972-) and Jennifer Lawrence (1990-), as well as the singer/actress Jennifer Lopez (1969-).
This spelling was used by Lord Byron for characters in The Giaour (1813) and Don Juan (1819), and it is through him that the name was introduced to the English-speaking world.
The name was common in France during the Middle Ages, and was introduced from there to England, though it eventually became rare. Interest in it was revived by the character Melanie Wilkes from the novel Gone with the Wind (1936) and the subsequent movie adaptation (1939).
