Jadis, of Latin origin, signifies 'formerly'. It was popularized by J.R.R. Tolkien's high elf character from "The Lord of the Rings" series. In French, it translates to 'formerly', while in Spanish and Italian, it means 'once upon a time'. This unique moniker is rarely encountered, lending an air of rarity and distinction to those who bear it.
"Jadis had its most popular year in 2007 with 22 births. However, it has seen a steady decline in popularity since 2010, with only 5 or fewer births per year from 2011 to 2023."
