Mordrain is Welsh in Origin.

Mordrain is a rare Arthurian given name from Old French romance, first attested in the 13th‑century Lancelot‑Grail (Vulgate Cycle). There it designates the eastern king Evalach/Evelake, who after conversion by Joseph of Arimathea takes the Christian name Mordrains and becomes a long‑lived hermit connected with the Holy Grail, later greeting Galahad. The figure reappears in later retellings, including the Post‑Vulgate and Malory, and so the name belongs to the Grail tradition rather than historical usage.

Variants include Mordrains, Mordreins, Mordrainus (Latinized), and Middle English Mordrayn; some sources list Evelake/Evalach as his earlier name. The etymology is uncertain and likely literary, with no secure meaning in French or Latin; modern bearers usually treat it as an evocative legendary name. Today Mordrain remains exceedingly rare, appealing to lovers of medieval lore and distinctive, archaic soundscapes.
