Meaning & origin
Lillis is an exceedingly rare feminine given name in the United States. It first appeared in official records in 1880, its peak year, and has remained consistently low in usage since then, rarely appearing in the top 1000. The name's trajectory is stable, having never experienced a significant revival. Due to its scarcity, no top states for the name were recorded. Lillis falls into the 1880s decade category, reflecting its origin during a period when elaborate floral and diminutive names were fashionable. Its exact derivation is uncertain, but it is commonly viewed as a variant of Lily or Lillian, both of which enjoyed broader popularity in the late 19th century.
Lillis is most likely a modern English variant or pet form of Lily or Lillian. Lily derives from the flower name, referring to the white Madonna lily, which has been used as a given name since the 19th century. Lillis may also have arisen as a diminutive of Elizabeth through its pet forms, though this is less certain.
