Einion is Welsh in Origin.

Einion is a Welsh masculine name from Old Welsh Einion, a noun meaning “anvil,” figuratively denoting firmness, stability, and steadfast strength. It belonged to the native Brythonic lexicon rather than biblical or continental sources, which helped mark it as distinctly Welsh across the Middle Ages.

The name appears frequently in early Welsh genealogies and chronicles: Einion Yrth ap Cunedda, a 5th‑century ruler of Gwynedd; Einion ap Owain of Deheubarth in the 10th century; and later literary figures such as Einion Offeiriad, a fourteenth‑century poet‑grammatian. Spelling fluctuated in Latin and English records, yielding forms like Eynon, Einon, Enion, and Enyon; these also survive as Welsh surnames. Modern usage is uncommon but benefits from the broader revival of Celtic heritage names. Related diminutive or feminine forms are rare, so Einion tends to stand alone, carrying a compact meaning of enduring resilience.
