What Irish Surnames Remember — Part 2: The Names That Came Ashore
Irish surnames are not only a story of Ó, Mac, Ní and Nic. They are also a story of arrival.
In Part 2 of What Irish Surnames Remember, we look at the names that came into Ireland through conquest, sea-roads, settlement, exile, work and migration — and how many of them became part of the Irish story.
From Norman names like FitzGerald, Burke, Power, Roche and Barry, to Norse-linked names like Doyle, MacAuliffe, MacManus, Cotter and MacIver, this episode explores how surnames can carry memory of contact across water.
We also look at names like Lynch, where one spelling can hide more than one history, and Walsh and Joyce, names that show how yesterday's outsider can become tomorrow's local surname.
Along the way, we ask:
When does a name become Irish?
Is it when it begins in Irish?
When it has an Ó or a Mac?
When it is spoken here?
When it is written into records here?
When it gathers Irish memory?
This episode also touches on later names that came ashore: Huguenot names, Jewish names, German names connected to Ardnacrusha, and Dutch names connected to Verolme Dockyard — reminders that Irishness was never purity. It was layering.
Core idea:
A name does not have to begin in Ireland to become part of Ireland.
In this episode:
Norman names: Fitz, de, Burke, Power, Roche, Barry and FitzGerald
"More Irish than the Irish themselves"
Surnames and placenames: names as maps
Norse and Viking traces: Doyle, MacAuliffe, MacManus, Cotter and MacIver
Why Lynch is a warning against simple surname stories
Walsh, Joyce and names crossing the Irish Sea
Huguenot and Jewish names in Ireland
German names at Ardnacrusha and Dutch names at Verolme Dockyard
Why Irish surnames are about contact, not purity
How Mac points us toward the upcoming Ireland–Scotland series
Next series:
After these two surname episodes, we cross the water into the Ireland–Scotland series: shared Gaelic worlds, language, myth, migration, colonisation, Highland and Irish experience, sectarian echoes, revolutionary links, and the sea-roads between the two places.

What Irish Surnames Remember — Part 1: Ó, Mac, Ní & Nic
Irish surnames are not just family labels. In this episode of Undercover Irish, we look underneath familiar names like O'Brien, Sullivan, McCarthy, Maguire, O'Neill and McBride to explore the older Irish naming system hidden inside them.
Before we cross the water into the upcoming Ireland–Scotland series, we pause to ask why names mattered so much: to families, to communities, and to colonial power.
We explore how Ó and Mac carry ideas of descent, sonship, clann and lineage — and how women's forms like Ní, Nic, Uí and Mhic reveal a richer grammar of relationship than English surnames usually show.
The episode also looks at the pressure of anglicisation: how Irish names were translated, shortened, misspelled, legally challenged, and pushed through English-speaking systems of law, schooling, census-taking and administration.
From Edmund Spenser's hostility to the Ós and Macs, to the symbolic court cases around Irish names and lettering, this episode asks what happens when a naming system is treated as something to be controlled.
Core idea:
If placenames are memory on the map, surnames are memory in motion.
In this episode:
Why O'Brien is really Ó Briain
What Ó / Ua means
How Mac and Mag work
Why Ní and Nic are not just "female versions" of surnames
What Bean Uí, Bean Mhic, Uí and Mhic reveal
How Irish names carry clann, kinship and memory
How colonialism and anglicisation fogged, but did not erase, the Irish naming system
Why this episode sets up the coming Ireland–Scotland series

When Ireland Speaks in a Woman's Voice: From Ériu to Elmes
Ireland was named after a woman.
Most of us know that Ireland is called Éire in Irish, but far fewer know about Ériu, the mythological figure whose name survives in the very name of the country itself.
In this episode of Undercover Irish, we follow the women hidden in Ireland's landscape. From Ériu, Banba and Fódla, to Boann and Sinann, from the holy wells of Brigid and Gobnait to the modern commemorations of Mary Elmes and the women of Cumann na mBan, we explore how women have been remembered on Ireland's map for centuries.
Along the way we delve into the Dindshenchas, Ireland's medieval "Lore of Places", uncover the stories behind some of our most famous rivers and placenames, and ask an important question:
If women are everywhere in Ireland's oldest landscape, why do they seem so much less visible in the streets and public spaces of modern Ireland?
This is a story about memory, mythology, language, landscape and the changing ways Ireland remembers its past.
In this episode:
Ériu, Banba and Fódla
The Dindshenchas – Ireland's Lore of Places
Boann and the River Boyne
Sinann and the River Shannon
Macha, Tailtiu and Carman
Brigid and the female sacred landscape

Ireland's county names are more than simple labels on a map.
They are records of invasion, settlement, religion, trade, conquest, resistance, and survival.
In Part 2 of What Irish County Names Really Mean, we explore how saints, Vikings, colonists, and mapmakers left their mark on Ireland's counties — and how older Irish identities survived beneath those layers.
Along the way we discover:
Why Dublin's Irish and English names describe two completely different places.
How Viking settlements helped create Ireland's first true cities.
The story behind Waterford, Ireland's oldest city.
Why Wexford, Wicklow, and Donegal preserve both Irish and Norse identities.
How Saint Brigid, Saint Cainneach, Saint Comán, and Saint Columba became immortalised in county names.
The connection between Derry's oak groves and Kildare's sacred oak.
Why Edmund Spenser believed language was key to conquering Ireland.
How the Ordnance Survey transformed Ireland's placenames.
Why Irish placenames are some of the most important historical records we possess.

What Irish County Names Really Mean – Gods, Tribes and Landscapes Before Ireland Had Counties
Follow Undercover Irish wherever you get your podcasts, and if you know someone who's fiercely proud of their county, send them this episode.
Because every county name tells a story — and some of those stories are over a thousand years old.

Ireland's counties feel ancient — but the county system itself is surprisingly modern.
In this episode of Undercover Irish, we go back before the maps, before English colonisation , and even before Christianity to uncover the real meanings behind Irish county names.
From pagan gods and forgotten tribes to marshes, forests, ridges, and sacred landscapes, many Irish counties preserve fragments of a much older Ireland hidden in plain sight.
In Part 1, we explore the counties whose names come from:
mythology,
tribal dynasties,
landscape and geography,
and ancient meanings now partly lost to history.
Along the way we uncover:
why County Armagh is named after a goddess,
how County Tyrone preserves the legacy of the O'Neills,
why County Cork is literally named after a swamp,
how County Mayo may preserve a sacred yew landscape,
and why nobody fully agrees on what County Limerick originally meant.
Counties featured in Part 1:
County Armagh
County Louth
County Kerry
County Fermanagh
County Tyrone
County Offaly
County Laois
County Cavan
County Clare
County Cork
