About Celtic names

"Celtic" covers two living branches and one that survives only in inscriptions. The Goidelic branch gives us Irish, Scottish Gaelic and Manx, with names like Aoife, Tadhg, Eilidh and Ruairidh and surnames built on Ó, Mac and Nic. The Brittonic branch gives us Welsh, Cornish and Breton, with Rhiannon, Gwilym, Kerensa, Jago, Nolwenn and Erwan and patronymics in ap and ferch. The oldest layer is Continental and British Celtic: chieftains recorded by Rome such as Vercingetorix, Boudica, Cassivellaunus and Cartimandua, whose names are compounds of words for king (rix), battle (catu), hound (cuno) and strength (nerto).

This list draws on all three. You will find ancient leaders and gods, heroes of the Ulster Cycle and the Mabinogion, medieval kings and poets, and modern full names in each language, including the Gaelic spellings of Scottish surnames and the feminine Ní and Nic forms that many generators forget. For fantasy use, the ancient and legendary names give the strongest flavour: they sound old because they are, and a character called Brannos or Arianrhod reads as unmistakably Celtic without borrowing a real modern surname.

How to choose Celtic names

  • Pick one branch and stay in it. A Welsh first name with a Scottish clan surname (Rhiannon MacLeod) is possible in the real world but reads as muddled in fiction; Rhiannon Powell or Eilidh MacLeod sounds rooted.
  • Learn the patronymic rules: Irish Ó and Mac take Ní or Nic for women (Ó Briain becomes Ní Bhriain), Scottish Mac becomes Nic, and Welsh ap (son of) becomes ferch (daughter of).
  • For ancient or fantasy settings, use the single-name Gaulish and British forms. Names ending in -rix, -maros and -gnatos are recognisably Iron Age and need no surname.
  • Check the accents. The fada in Irish (Seán, Síofra) and the grave in Scottish Gaelic (Mòrag, Dòmhnall) mark long vowels and change pronunciation; dropping them is the commonest tell of an outsider.
  • If players or readers will say the name aloud, favour names whose spelling matches English expectations (Finn, Bran, Nia, Owain) over ones that do not (Caoimhe, Siobhán) unless you are happy to coach them.

Frequently asked questions

What counts as a Celtic name?

Any name from the Celtic-speaking peoples: Irish, Scottish Gaelic and Manx (Goidelic), Welsh, Cornish and Breton (Brittonic), and the ancient Gaulish, Celtiberian and British tribes known from Roman sources and inscriptions. This generator includes all of them.

Can I use these names for a fantasy character?

Yes. The ancient single names (Brennus, Catumaros, Segovax), the legendary names (Cú Chulainn, Arianrhod, Taliesin) and the old gods (Taranis, Epona, Cernunnos) all work well in fantasy, while modern full names suit historical fiction or a grounded setting.

What is the difference between Gaelic and Celtic names?

Gaelic names are one branch of Celtic, covering Irish, Scottish Gaelic and Manx. Welsh, Cornish and Breton names are Celtic but not Gaelic. Calling Rhiannon a Gaelic name is a common mistake; she is Welsh.

How are the ancient names pronounced?

Roman-era Celtic names are usually read as written with Latin vowels: Vercingetorix is ver-kin-GET-o-rix, Boudica is BOO-dih-ka, Cunobelinus is koo-no-be-LEE-nus. The 'c' is always hard and 'ix' rhymes with 'six'.
