Lilias, a feminine given name rooted in Scottish Gaelic heritage, derives etymologically from the Latin term lilium (lily) and functions historically as a variant of Lillian; its original Gaelic pronunciation, /ˈliːliəs/, coexists with the anglicized form, /ˈlɪliəs/, employed in contemporary English usage. The name’s botanical association with the lily flower imbues it with connotations of purity, innocence, and renewal, characteristics that have informed its modest but enduring appeal. Examination of United States Social Security Administration data since the early 20th century indicates sporadic yet persistent registrations—beginning with eight occurrences in 1915 (rank 556) and intermittent mid-century appearances, followed by a gradual resurgence in the early 21st century, including eight newborns in both 2018 and 2021 (ranks 949 and 939, respectively) and ranking 942 in 2024 with eight bearers—underscoring its sustained niche status among anglophone parents seeking a historically resonant appellation distinguished by both traditional gravitas and contemporary rarity.
