Jacilyn is of American origin, derived from two popular names: Jacqueline and Lynn. It combines the elegance of Jacqueline, which means 'little jaqueline,' and the charm of Lynn, a shortened form of Cunigunde meaning 'kings' daughter.' Jacilyn thus suggests a harmonious blend of sophistication and warmth.
The name Jacilyn peaked in popularity between 1977 and 1984, with a high of 22 births in 1984. However, it has since become much less common, with only 5 births recorded in 2021. Overall, there were 386 babies named Jacilyn between 1974 and 2021.
