Merilyn as a Baby Name. Meaning and Origin of Merilyn

What is the meaning of the name Merilyn ?

The baby name Merilyn is a Female name , 3 syllables long and is pronounced MEH-rih-lin (IPA: /ˈmɛrɪlɪn/).

Merilyn is English in Origin.

Merilyn is a modern English feminine given name, most commonly a variant spelling of Marilyn, formed from Mary + Lynn and pronounced MER-ih-lin. The name’s meaning draws from its elements: Mary, of debated Hebrew origin (interpreted as “beloved,” “wished-for child,” or “drop of the sea”), and Lynn, from Welsh llyn, “lake; waterfall.” As a blended modern coinage, Merilyn is typically read as a stylistic respelling rather than a separate etymology, and it is distinct from the masculine Celtic Merlin.

Documented in English‑speaking countries from the 1930s onward, Merilyn rose alongside Marilyn’s mid‑century fame - especially in the United States, Britain, and Australia - before declining after the 1970s. Variant forms include Merrilyn, Merilynn, and Marilynn; closely related names are Marilyn, Meryl (from Muriel), and Meriel. Nickname options range from Meri/Merry to Lyn. The name retains a vintage, mid‑century glamour while offering a softer twist on the more familiar Marilyn.
