Karilyn is a unique and melodic feminine given name, a variant of Karina but with an extra 'l' at the end. Its origin can be traced back to the Latin word 'carus', meaning beloved or dear, via the Germanic name Cara. The 'lyn' suffix makes it reminiscent of names like Dylan and Lynn, adding a modern touch to its classic roots. Karilyn is also associated with the Irish surname O'Lynch, further enriching its cultural heritage.
"The name Karilyn had a notable rise in popularity from the late 1950s onwards, with over 10 births annually between 1959 and 1964. However, it experienced a significant decline thereafter, dropping below double digits by 1973. After fluctuating around this low point for several decades, there was another notable spike in the late 1980s to early 1990s, but since then, its usage has steadily declined, with fewer than 10 births annually recorded from 2006 onwards."
