Cybil is an uncommon yet striking feminine given name of Latin origin, derived from the Roman family name Cybius, which is believed to be Etruscan in origin. The name Cybil is thought to mean "of the Cybil people," potentially referencing an ancient Italian tribe or a goddess venerated by them. This unique name has been largely unused throughout history, making it a distinctive choice for parents seeking an unusual yet classic name for their daughter.
Cybil had a peak popularity in the mid-70s with a significant spike in 1972 and remained relatively common until the late 80s. After that, it steadily declined in usage, becoming quite rare by the early 2000s. Recent years have shown a slight uptick in its usage, but it's still not as popular as it was during its peak decades. Overall, Cybil has been given to over 500 girls over the past 53 years.
