Kersti is a name of Estonian origin, derived from the given name Kersten. It means "Christian" or "follower of Christ," reflecting its roots in the Latin word 'Christianus'. The name gained popularity in Estonia during the Middle Ages and has since become one of the country's most traditional female names. Today, Kersti is still widely used in Estonia and among Estonian communities abroad, carrying with it a sense of cultural heritage and pride.
The name Kersti experienced a notable spike in popularity between 1990 and 1991, with 18 births recorded in 1990 and 13 in 1991. However, it's important to note that there were fewer than 10 births annually for most other years between 1969 and 1994, suggesting a decline in popularity during those periods. Overall, the name Kersti was given to 62 babies over this 25-year span.
