Ceilia is of Latin origin, derived from the masculine form Cecil. It means 'sixth' and was traditionally given to children born on the sixth day of the month. The name gained prominence during the Middle Ages in England, where it was often used as a feminine form of Cecil. However, its usage has become quite rare today.
"Ceilia gained popularity among parents between 1984 and 1985, with a total of 11 babies named Ceilia born during this period."
