Maelwys is Welsh in Origin.

Maelwys is a Welsh/Brythonic masculine name built from the elements mael “prince, chieftain” and gwas “youth, servant.” Through historical sound changes and orthographic variation, it appears as Maelgwas and Melwas, with Maelwys reflecting a later Welsh spelling tradition. The sense is usually taken as “princely youth” or “servant of the prince,” and it belongs to the same Celtic name family as Maelgwn and Maelwyn that center on the noble element mael.

The name is attested in medieval Welsh and broader Arthurian material: Melwas (Latinized Meluas) is the king who abducts Guinevere in sources such as Caradog of Llancarfan and later romances, a tale echoed in the French Meleagant. As a given name, Maelwys became rare after the Middle Ages but sees occasional modern revival in Wales. Variants and related forms include Maelgwas, Melwas, Maelwas, Maelgwn, and Maelwyn.
