Myrddyn is Welsh in Origin.
Myrddyn is a Welsh/Brythonic name tied to the place‑name Moridunum, the Roman-era ‘sea-fortress,’ which became Welsh Caerfyrddin (Carmarthen). Through folk etymology, the toponym yielded the personal name Myrddin; Myrddyn is a rare modern spelling. Because of this origin, the name is often glossed as ‘sea-fortress’ or interpreted as ‘of Carmarthen,’ rather than carrying an independent lexical meaning in Welsh.
It appears in early Welsh tradition as Myrddin Wyllt, a northern bard-turned-wild seer of the 6th century. Geoffrey of Monmouth recast him as the prophet-wizard Merlin, Latinizing the name to Merlinus to avoid an unfortunate resemblance to Latin merda; from there, the Merlin form spread widely in Arthurian literature. As a given name, Myrddin/Myrddyn saw limited use until modern Welsh cultural revivals and remains uncommon. Variants and cognates include Welsh Myrddin (standard), English Merlin, Latin Merlinus, Breton Merzhin, and Cornish Marzhin.
We can't find Myrddyn in any of the birth registries or name datasets we track. Names like this are usually very rare, tied to a particular region or tradition, or freshly invented. Whatever the reason, hardly anyone else has it.
