Lucy is the English form of the Latin Lucia and means "light", from lux; Saint Lucy, whose feast falls in the darkest days of December, made it a name of candles and light. Lucille Ball's I Love Lucy and the Beatles' Lucy in the Sky with Diamonds are its American pop-culture landmarks. Lucy stood at number 324 in 2000, reached the top 100 in 2010 and ranks twenty-fifth in 2025, its highest rank since the 1920s.
