Will the generator give me different Irish registers — not just modern Republic?

Yes — it rotates across ten registers from medieval Gaelic to penal-era Anglo-Irish to modern Republic to Northern Ireland (both Catholic / Nationalist and Protestant / Unionist) to Ulster Scots to the Travelling Community to multiple diaspora communities. Regenerate if you want a specific register.

Will I get Irish-language given names with pronunciation guides?

Yes — modern Republic and Northern Ireland Catholic register names are returned in Irish-language form (Aoife, Caoimhe, Cillian, Niamh, Oisín) with pronunciation guides. Anglicised forms are returned for the penal-era, diaspora, and Northern Ireland Protestant registers.

Are the Travelling Community names appropriate to use respectfully?

Yes — the Mincéirí / Pavees onomastic tradition is part of the Irish onomastic tradition, and the surnames (Connors, Joyce, Ward, Maughan, McDonagh, Stokes) and given names (Catholic-saint-derived) are real. The generator produces characters with specific community dignity rather than stage-Traveller caricature; treat the community context with appropriate respect.

Will the names work for Celtic fantasy roleplaying?

Yes — the medieval Gaelic register maps cleanly onto Celtic-inspired fantasy settings (D&D's Tír na nÓg, Pathfinder's Iobaria, Forgotten Realms' Moonshae Isles). Use the clan-affiliation field to ground the name in your setting's analogue of the Uí Néill / Eóganacht / Cenél Conaill clan-structure.

Why does the schema use 'backstory' and 'personality'?

The site shares one schema across all generators. For Irish names, 'backstory' is the character's regional, family, and migration origin, 'personality' is the daily texture (languages spoken, religious practice, sport followed, drink), and 'plotHook' is the current situation (a family illness, a partnership offer, a dissertation methodology question).

Irish Name Generator

Medieval Gaelic to modern Irish to diaspora — full given + surname structure with provincial register.

Aoife Ní Shúilleabháin

EE-fah nee HOO-il-uh-vawn·Modern Republic of Ireland name in the bilingual Irish-language register. 'Aoife' (modern Irish spelling, pronounced EE-fah) is a Classical Irish given name derived from Old Irish aoibh, 'beauty' or 'radiance'; the name has been continuously in use for over a thousand years and was strongly revived in the 1980s-1990s and remained in the top-10 Irish-language female given names for the entire 2000s-2010s decade. 'Ní Shúilleabháin' is the feminine form of the surname Ó Súilleabháin ('descendant of Súileabhán,' a 10th-century Munster chieftain whose own name meant 'little dark-eyed one'); the form Ní is the modern Irish-language feminine equivalent of the masculine Ó. The anglicised form is O'Sullivan. The family's traditional origin is the Beara peninsula in West Cork.

Backstory

Aoife was born in Cork city in 1991, the second of three siblings. Her father (Pádraig Ó Súilleabháin, born 1962, Beara-born and Cork-raised) is a senior software engineer at a Cork-based multinational; her mother (Sinéad Ní Mhurchú, born 1965, originally from Galway) is a senior secondary-school teacher of Irish and history. The family lived in Douglas (a Cork suburb) and Aoife attended an Irish-medium secondary school. She studied medicine at University College Cork (graduating 2015) and is currently a senior registrar in paediatric oncology at a Dublin children's hospital, in the final two years of her specialty training. She is engaged to be married in summer 2027 to a Donegal-born colleague.

Personality

Bilingual in Irish and English — uses Irish at home with her parents and brother, English at work and with most Dublin friends. Practises Catholicism culturally rather than observantly — goes to mass at Christmas and Easter, baptised her partner's nephew, would describe herself as 'lapsed' in a tone that suggests it is not a settled question. Drinks builder's tea in the morning, a single glass of red wine with dinner. Plays camogie (the women's GAA hurling-equivalent) for a Dublin club at weekends; her father played hurling for Cork at minor and U21 level in the early 1980s. Follows Cork in the GAA football and hurling championships without fail and rugby (Munster) at the provincial level.

Plot hook

**Aoife's father has been diagnosed in the past month with an early-stage but aggressive cancer requiring immediate chemotherapy. The diagnosis was made at a Cork hospital and the family is choosing between continuing care in Cork (with the consultant her father has known for fifteen years) and transferring to Dublin (where Aoife herself is on staff at the city's leading paediatric oncology centre, but where the relevant adult-oncology consultant is a colleague of Aoife's who would feel an awkward professional obligation). Aoife's mother is unequivocally in favour of the Dublin transfer; her father is undecided; her older brother (an investment banker in London) has, this week, told Aoife that he will support whatever Aoife and the consultants think is best, which Aoife has read as her brother declining to take a position. Aoife has not yet given her own preference to her father.**

About this Irish name generator

An Irish name is a register. 'Aoife Ní Shúilleabháin' commits to modern Republic of Ireland bilingual Irish-language Catholic-cultural professional. 'Bridget Connors' commits to Mincéirí Traveller Community Catholic-observant adult-learner. 'James Crawford' commits to Northern Ireland Protestant / Unionist Ulster Scots Presbyterian commercial-law. Most online Irish-name generators collapse all of these into a single 'O'Reilly-and-Murphy' stage-Irish paste. This Irish name generator doesn't, and that is what it is built for.

Each result draws on real Irish onomastic scholarship — the medieval Brehon-Law clan-and-patronymic system (Mac- / Ó-), the late-medieval Norman-Gaelic assimilation (Burke / Fitzgerald / Roche), the penal-era anglicisation that dropped the Mac- and Ó- prefixes, the modern Republic's Irish-language revival, the distinct Northern Ireland Catholic / Nationalist and Protestant / Unionist registers, the Ulster Scots tradition, the Mincéirí / Pavees Travelling Community onomastic tradition, and the substantial Irish-American / Australian / British-Irish diaspora communities.

The registers the generator rotates

Medieval Gaelic: 600-1200 CE, Brehon-Law, Mac- / Ó- + clan.

Late medieval / Norman-Gaelic: 1200-1600 CE, Norman surnames adopted.

Penal-era Anglo-Irish: 1690-1840, Mac- and Ó- formally dropped.

Modern Republic of Ireland: 1922-present, Irish-language revival.

Northern Ireland Catholic / Nationalist: Ó- preserved or anglicised.

Northern Ireland Protestant / Unionist: Scots-Irish, Old Testament given names.

Ulster Scots: Lowland Scots given names + surnames.

Travelling Community / Mincéirí: Catholic saint-name + Traveller surname.

Irish-American diaspora: Anglicised, saint-name + Boston / Chicago / NYC.

Irish-Australian / Canadian / British-Irish diaspora: Anglicised with regional flavour.

How Ó, Mac, Ní, and Nic work

An Irish surname is built from a relationship word. Mac means 'son of'; Ó means 'grandson' or, more loosely, 'descendant of.' So Mac Cárthaigh is 'son of Cárthach' and Ó Súilleabháin is 'descendant of Súileabhán.' The piece that trips up most generators is the feminine. A woman does not take Mac or Ó. A daughter of an Ó- family becomes Ní, a contraction of iníon Uí, 'daughter of the descendant of'; a daughter of a Mac- family becomes Nic, from iníon Mhic. That is why the generator returns Aoife as Ní Shúilleabháin rather than Ó Súilleabháin, and why the surname's first consonant softens to add that 'h' (Súilleabháin becoming Shúilleabháin) — Irish lenites the name after these particles.

Then there is the history layer the generator rotates through. Under the Penal Laws and the long anglicisation that followed, a great many families dropped the Ó and Mac entirely: Ó Ceallaigh flattened to Kelly, Mac Gabhann to Smith or McGowan, and the apostrophe in O'Brien is really an English printer's attempt at the Irish fada over the Ó. After independence in 1922 many families restored the Gaelic form, which is why a single bloodline can hold Ó Súilleabháin, O'Sullivan, and Sullivan across three generations. Picking a register is therefore also picking a moment in that long swing between Irish and English forms.

What you get

Each result returns a full Irish name (with bilingual Irish-and-English forms where relevant), a pronunciation note (respecting Irish-language phonology where applicable), an etymology + register + historical period paragraph, a backstory (place of birth, family, profession, generation), a daily-life paragraph (languages spoken, religious or secular practice, sport followed, drink of choice), and a current situation a writer or GM can use.

How to use the names

For historical fiction set in any Irish period — Brehon-era Munster, Norman Connacht, Penal-era Cork, 1916 Dublin, Troubles-era Belfast, contemporary Limerick — the names plug in directly with their period-appropriate register. For contemporary fiction, the modern Republic, Northern Ireland (both registers), Traveller Community, and diaspora registers are all distinct and each works without adjustment. For Celtic-inspired fantasy roleplaying (D&D's Tír na nÓg-style settings, Pathfinder's Iobaria, Glorantha's Esrolia-as-Celtic-analogue), the medieval Gaelic register integrates cleanly.

Why register matters more than 'Irishness'

A Cork doctor in Dublin in 2026, a Lisburn solicitor in London, a Limerick Traveller community sociologist, and a 12th-century Eóganacht Chaisil princess are four genuinely different cultural artefacts even though all four are Irish. The generator commits to one register per result, gives you the cultural-specific structure and the small details (tea preference, mass observance, sport followed) that distinguish the register, and produces a character whose dignity is specific to that register rather than to a generic 'Irish' archetype.
