Lilia comes from the Latin lilium and means "lily", the white flower that stands for purity in Christian art; it is the Spanish, Italian and Russian form of the flower name and sits between Lily and Lillian in sound. It has long been used in Mexico and Eastern Europe. Lilia entered the US top 1000 in 2023 after hovering just outside for years and ranks number 859 among girls in 2025, its best rank so far.
