Keelyn, of Irish origin, is a unique and melodic name that has gained popularity in recent years. It's derived from the Irish surname 'O'Caoilfhinn,' which means 'descendant of Caoilfinn.' Caoilfinn itself is believed to be composed of the elements 'caol' meaning 'slender or fair-haired,' and 'find' meaning 'white or fair.' Therefore, Keelyn could be interpreted as a name that signifies fairness or beauty. It's often associated with the feminine form, although its use has been quite versatile in recent times.
The name Keelyn experienced significant growth in popularity from the late 1990s to around 2010, with a peak of 70 births recorded in 2010. However, since then, its popularity has steadily declined, with only 10 births recorded in both 2021 and 2023. Overall, there have been a total of 848 babies named Keelyn since 1973.
