Charlii is of American origin, derived from the English word 'charley,' which means 'free man.' The name gained popularity in the late 20th century and has been used as both a given name for girls and occasionally as a unisex name. It typically appears in spelling variations like Charlie or Charlee, but Charlii is less common. The name does not have any associated saints or feast days, making it secular in nature.
"Charlii experienced a significant spike in popularity between 2016 and 2018, with a peak of 16 births in 2016 and 12 births in both 2017 and 2018. However, there has been a steady decline since then, with only 7 births each in 2022 and 2023."
