Leoline as a Baby Name. Meaning and Origin of Leoline

What is the meaning of the name Leoline ?

The baby name Leoline is a Male name , 3 syllables long and is pronounced LEE-oh-leen (IPA: /ˌliː.oʊˈliːn/) — also heard as leh-OH-leen.

Leoline is Latin, Welsh in Origin.

Leoline is an Anglicized, slightly Latinate elaboration of the Welsh royal name Llywelyn. Its first element is usually traced to Welsh llyw “helm, governance, leadership,” with the second element uncertain, giving an overall sense of “leader” or “ruler.” The spelling’s leo- has long encouraged association with Latin leo “lion” and Welsh llew “lion,” so in English ears the name carried a subtly leonine, chivalric tone.

Attested in Wales and England from the early modern period - most famously borne by Sir Leoline Jenkins (1625–1685) - the name gained Romantic-era visibility through Coleridge’s Christabel, whose patriarch is Sir Leoline. Never common, it saw a mild Victorian revival and remains rare today. Variants and cognates include Leolin, the Latinized Leolinus, and the Welsh forms Llywelyn, Llewelyn, and Llewellyn; Leoline also appears occasionally as a feminine given name in 19th‑century records. Overall meanings cluster around “leader, ruler,” with a traditional “lion-like” overtone.
