Merwin is English in Origin.

Merwin blends two intertwined traditions. In Anglo-Saxon England it reflects Mærwine or Merewine: mær or mere (interpreted as “famous” or “sea”) + wine (“friend”), giving readings such as “famous friend” or “friend of the sea.” In Wales, its close cousin Mervyn goes back to Old Welsh Merfyn, borne by the 9th-century ruler Merfyn Frych; while the exact elements are debated, the name was firmly rooted in medieval Welsh usage. Middle English records show spellings that lead naturally to the modern Merwin.

Used as both a given name and a surname in England, Merwin later gained modest popularity in North America, peaking in the early 20th century and now rare with a vintage feel. Variants and cognates include Merwyn, Mervyn, Mervin, and Marvin; the Welsh Merfyn is the historical source. Modern name guides often favor the senses “famous friend” or “sea-friend.”
