Kaylee is a charming and distinctive given name of American origin, derived from the Irish surname 'Keeley' which was originally an anglicized form of the Gaelic 'Mac Caollaidh', meaning 'son of the bright-headed one'. The name Kaylee gained significant popularity in the late 20th century, peaking in the United States during the early 2000s. It is often considered a modern-day alternative to more traditional names like Kay or Leigh, offering parents a unique yet familiar option for their children.
The name Kaylee experienced a significant surge in popularity between the years 2003 and 2004, with an increase from 7 to 47 births in just one year. This spike is quite remarkable and suggests that there might have been some notable cultural influence or event during this period that led to its sudden rise in popularity among parents choosing names for their daughters. However, the name's popularity appeared to decline somewhat after 2004, with totals varying between 5 and 11 births per year until 2015.
