Maelgwn is Welsh in Origin.

Maelgwn is a Welsh masculine name from early Brittonic roots, built from mael “prince, chieftain” and gwn < *cuno- “hound.” Latin sources render it Maglocunus, reflecting Proto-Celtic *maglos (chief) + *kūnos (hound), yielding the sense “hound-prince” or “princely hound,” a heroic epithet signaling leadership and martial prowess. Despite visual similarity, the second element is not gwyn “white; blessed.” Its best-known bearer is Maelgwn Gwynedd, a powerful 6th‑century king cited by Gildas, and the name appears in the Annales Cambriae and later Welsh pedigrees. Use waned after the medieval period, resurfacing sporadically during 19th–20th‑century Welsh cultural revivals, and it remains rare today. Variants and spellings include Maelgwyn, Maelgun, and the Latin Maglocunus; related by element are Irish/Scottish Con‑ names (from cú “hound”) and Welsh Gwyn as a separate, not equivalent, name.
