Where did the name Marvin originate?

The name Marvin originated in Wales as a variant of the Welsh name Mervyn, with roots going back to ancient Celtic language. Marvin comes from the Welsh name Merfyn or Mervyn, which is derived from two Old Welsh elements, mer meaning sea or marrow, and myn or vyn meaning hill or eminent, so it is interpreted as sea hill, hill by the sea, or great lord. The name Merfyn was borne by early Welsh kings, such as Merfyn Frych, King of Gwynedd in the 9th century. Over time, Mervyn was anglicized to Marvin in England and later in America. The name came to the United States with Welsh and English immigrants and became popular in the early 20th century, peaking in the 1930s to 1960s. Some sources also suggest a secondary origin from the Old English name Mærwine, from mær meaning famous and wine meaning friend, meaning famous friend, but the Welsh origin is more widely accepted. The name Marvin is therefore Celtic-Welsh in origin, meaning sea friend or sea hill, and spread through English-speaking countries, becoming especially popular in America due to figures like Marvin Gaye. It retains its Welsh heritage while being used worldwide today, especially in the US, Germany, and Scandinavia where it has seen recent revival as a vintage name.
