Merline is in Origin.

Merline is a feminine given name with two intersecting roots. As the feminine counterpart to Merlin, it traces to Welsh Myrddin, popularized in medieval Arthurian legend and Latinized as Merlinus by Geoffrey of Monmouth. The underlying meaning is debated but is often linked to Welsh mor “sea” + din/dinas “fort; hill-fort,” yielding a sense of “sea-fort” or “fort by the sea.” In a French context, Merline can also arise independently from merle “blackbird” with the feminine suffix -ine, giving the poetic meaning “little blackbird.”

Use as a given name grew with 19th–20th century interest in Arthurian themes and has seen steady, if modest, presence in French-speaking regions and the Caribbean (notably as Mérline). Related forms and variants include Merlin (masculine/unisex), Merlyn, Merlina, Merlyne, and Merlynne; diminutives like Merli or Merlie sometimes appear. The name balances mythic resonance with a lyrical, avian French nuance.
