Names
Irish Name Generator
Selecting from pools of 20 male first names (Ciarán, Tadhg, Oisín, Diarmuid, Lorcan, and others), 20 female first names (Aoife, Caoimhe, Saoirse, Muireann, Dearbhla, and others), and 20 surnames (O'Brien, Fitzpatrick, Gallagher, Kavanagh, and others), the generator picks one first name and one surname at random and concatenates them. When gender is set to "any", the function flips a coin between the male and female pools for each name independently; setting it to "male" or "female" restricts all draws to that pool. Count controls how many full names are returned, up to 20. Writers working on Irish-set fiction, game designers building authentic rosters, and people exploring family heritage all rely on this tool for the same reason: placeholder names that merely sound Gaelic read as invented, while names drawn from actual Gaelic tradition carry the phonological patterns — the dh, bh, and mh digraphs, the fada accent, the O' prefix — that signal genuine Irish origin. A novelist naming a County Clare side character, a tabletop GM populating a Dublin campaign, or a genealogy hobbyist brainstorming possibilities can each generate a batch of 10 or 20 and pick whichever combination fits. The surnames in the pool are among the most historically documented in Ireland: Murphy, Walsh, Collins, O'Neill, Nolan. The first names span medieval saints, mythological figures, and names common in modern Ireland. No elements are fabricated — every name in both pools appears in Irish naming records.

Detailed instructions
- Set the count field to how many names you want — start with 10 to give yourself a decent selection pool.
- Choose a gender from the dropdown if you need specifically male or female names, or leave it on any for a mixed list.

- Scan the results and note any names that fit your project — regenerate as many times as needed to find the right combination.
- Copy your chosen name and look up its pronunciation on Forvo.com or the Foclóir.ie dictionary before using it publicly.
Use Cases
- •Naming a cast of 10+ characters for a historical novel set in 19th-century rural Ireland
- •Generating NPC rosters for a Celtic-themed TTRPG or video game with authentic Gaelic feel
- •Building a realistic placeholder family tree in a genealogy tool like Ancestry or MyHeritage
- •Shortlisting baby names for families with Irish heritage before cross-checking pronunciation on Forvo
- •Creating an Irish-identity brand name for a podcast, band, or small business
Tips
- →Generate a large batch of 15-20 names at once — Irish names often look similar until you read them aloud, and volume helps you spot the one that clicks.
- →For female characters in authentic Gaelic contexts, pair the generated first name with a Ní prefix on the surname — Niamh Ní Cheallaigh reads far more genuinely Irish than Niamh Kelly.
- →If you're worldbuilding, mix one well-known surname like Murphy with a rarer first name like Earnán or Lasairfhíona to balance recognisability with distinctiveness.
- →Avoid generating names and then anglicising the spelling — Caitlin and Cáitlín are essentially different names with different cultural weight; keep the original form.
- →For historical fiction set before the 17th century, favour older Gaelic names like Gofraidh, Muirchertach, or Étaín over names that became common only post-Christianisation.
- →When naming multiple characters in the same fictional family, regenerate until you find a surname you like, then lock it and use the generator's first name variety to give each character a unique given name.
FAQ
How does the generator decide which first-name pool to use?
Selecting "male" restricts every draw to the male first-name pool; "female" restricts to the female pool. Choosing "any" makes the generator flip a random coin for each individual name independently, so a batch of five on "any" may return any mix of male and female first names. Surnames are drawn from a single shared pool regardless of the gender setting.
How do you pronounce names like Caoimhe, Siobhán, or Tadhg?
Irish phonetics diverge sharply from English spelling conventions. Caoimhe is KEE-va, Siobhán is shih-VAWN, Tadhg is TYE-g, and Aoife is EE-fa. The letter combinations bh and mh produce a V or W sound, and many consonants are silent in certain positions. Forvo.com has native-speaker audio recordings for most of these names if you need a reliable reference.
What do the O' prefixes in surnames like O'Brien or O'Connor mean?
O' derives from the Irish Ó, meaning 'grandson of' or 'descendant of', making O'Brien literally 'descendant of Brian'. It is a patronymic prefix that became hereditary around the tenth and eleventh centuries. The apostrophe in the anglicised spelling represents the omitted vowel from the original Irish word.
Are the names drawn from real Irish tradition or invented for the generator?
Every name in both the first-name and surname pools is documented in Irish history, mythology, or modern Irish census records. None are invented phonetic approximations. Names like Fionnuala and Cormac appear in early medieval manuscripts; names like Saoirse and Caoimhe are among the most commonly registered in Ireland today. The spellings follow standard Irish orthography.
Can the same name appear more than once in a single batch?
Yes. The generator samples with replacement from fixed pools of 20 first names and 20 surnames, so a batch of 20 names could theoretically repeat a first name or a surname. In practice, exact full-name duplicates are uncommon in smaller batches, but if uniqueness matters, scan the results before using them.
