Cersei is of Latin origin, derived from the word 'caesar', meaning 'to cut'. It was traditionally given to children born around harvest time, as the Roman festival of Caesar took place during this period.
"The name Cersei experienced a notable drop in popularity between 2017 and 2019, with only six births recorded that year, compared to the eleven registered two years prior. However, it seems to have regained some traction subsequently, with seven births each in 2021 and 2023. Overall, there were thirty-seven babies named Cersei born between 2017 and 2023."
