Lilieth is a modern elaboration of Lily, the flower name that stands for "lily" and, by tradition, for purity, with an ending that recalls Lilith or Elizabeth. The name has been used for decades in Jamaica and the Caribbean, which is where most American bearers trace it to. It was almost unknown in US birth records until it jumped to number 1581 in 2024 and ranks 2183 in 2025, with 85 girls given the name.
