Irish Surnames from County Galway: Origins, Meanings and Heritage

County Galway holds some of Ireland’s most distinctive family names. If your surname traces to Galway, your name was shaped by Gaelic clans. They farmed the plains of Connacht and fished the Atlantic coast. This guide covers Irish surnames from County Galway — what they mean, where they come from, and what they say about your past.

Why Galway Names Are So Distinctive

Galway covers over 6,000 square kilometres. It runs from the Atlantic coast to Connemara bog and the flat plains of east Galway. The Aran Islands lie just offshore. For centuries, this was the heart of the old province of Connacht. Great Gaelic clans ruled here. The O’Flahertys, the O’Kellys, and the Hynes were the most powerful.

The Normans arrived in the 12th and 13th centuries. Families such as de Burgo — later Burke — settled in the county. Within a few years, they adopted Irish customs and the Irish language. Ancient Gaelic names now sit beside Norman-Irish names that feel entirely native to the county.

During the Great Famine of the 1840s, an estimated 25,000 people left County Galway. Many sailed from the port of Galway or travelled south to Cobh in Cork. Their children and grandchildren spread across the United States, Canada, Australia, and Britain. About 7 million Americans claim Galway roots.

The Most Common Galway Surnames and Their Origins

Here are the surnames most closely tied to County Galway, with their Gaelic roots and history.

Burke (de Burca)

Burke is the most common surname in County Galway. It comes from the Norman de Burgo family. They arrived in Connacht in the 12th century. Within a few years, they took the Irish form de Burca. By the 14th century, the Burkes ranked among the most powerful lords in the west of Ireland. They held vast estates across Galway and Mayo. Today, Burke ranks 6th most common in all of Ireland — but it clusters most densely in Galway.

O’Flaherty (Ó Flaithbheartaigh)

O’Flaherty means “bright ruler.” The O’Flaherty clan ruled west Connacht for centuries. They held Iar Connacht. The pirate queen Gráinne Ní Mháille (Grace O’Malley) married an O’Flaherty chief. In the 1650s, Cromwell’s forces drove the O’Flahertys off most of their lands. The name lives on today as Flaherty, Flahery, and Laherty.

O’Kelly (Ó Ceallaigh)

Kelly is one of the most common surnames in Ireland. But the O’Kelly clan of east Galway has its own distinct and ancient line. The Ó Ceallaigh family ruled Uí Maine — a kingdom that covered much of east Galway and south Roscommon. Their name means “descendant of Ceallach,” a word meaning “strife.” They made Loughrea, County Galway, their seat of power. They ruled from there for over 400 years.

Lynch

Lynch takes its roots from Galway city. The Lynches were one of the “Tribes of Galway.” These were 14 merchant clans who ran the walled port from the medieval era to the 17th century. Their Norman roots trace to the Old French de la Linche. The family served as Mayor of Galway over 84 times between 1400 and 1654. Lynch’s Castle stands on Shop Street today. Built in the early 16th century, it is one of the finest old town houses in Ireland. A bank now occupies it.

Hynes (Ó hEidhin)

Hynes is one of the most uniquely Galway names in all of Ireland. The Ó hEidhin clan ruled Aidhne in south Galway — the land between the Burren and the Clarin river. The name means “descendant of Eidhin.” The Hynes clan held their ground in south Galway the longest. If your name is Hynes, County Galway is almost certainly where your people came from.

Connelly / Conneely (Ó Conghaile)

Connelly and Conneely both come from the Gaelic Ó Conghaile. The clan lived in the barony of Moycullen, west of Lough Corrib. The name means “descendant of Conghal” — blending words for “hound” and “valour.” On the Aran Islands, Conneely is still among the most common names. Some families on Inis Mór and Inis Oírr have farmed the same land for more than 500 years.

Naughton (Ó Neachtain)

Naughton comes from the Gaelic Ó Neachtain, meaning “pure one.” The Ó Neachtain clan formed part of the O’Kelly sept. They held land in east Galway for centuries. The name appears in many anglicized forms: Naughton, Naghten, and sometimes Norton. English clerks often misread the Gaelic original when they wrote down Famine-era emigrant names.

The Tribes of Galway: Merchant Clans Who Ran the City

No account of Galway names is complete without the Tribes of Galway. These were 14 merchant clans of Norman or Welsh origin. They ran the walled port from the 13th century until 1652. Cromwell’s forces took the city that year. If your name appears below, your Galway roots may trace to these old trading clans.

• Athy — possibly from Athy in County Kildare.
• Blake — from the Norman name le Blaec (the dark one).
• Bodkin — a Galway family of Norman descent.
• Browne — from the Norman le Brun (the brown-haired one).
• D’Arcy — from Arcy in Normandy, France.
• Deane — from the Old French dehen (valley).
• Font — possibly from the French font (spring or fountain).
• French — a family who came from France.
• Joyce — possibly from the Breton name Iodoc.
• Kirwan — an Irish-Norman family; the name may link to Ciaran.
• Lynch — see above; Mayors of Galway 84 times between 1400 and 1654.
• Martin — from the Latin Martinus (of Mars).
• Morris — from the Latin Mauritius (Moorish).
• Skerrett — an English family who settled in Connacht.

These clans intermarried with Gaelic families across three centuries. A DNA test may show links across more than one of the Tribes. That reflects the dense web of ties that held Galway’s merchant world together.

Connemara and the Aran Islands: The Gaelic Heartland

West Galway — Connemara and the Aran Islands — stayed almost Irish-speaking into the 20th century. Names from this area are among the oldest and most distinctly Irish in the county.

• Conneely (Ó Conghaile) — one of the most common names on the Aran Islands; closely tied to the Connemara coast.
• Flaherty (Ó Flaithbheartaigh) — the ruling clan of western Connacht for centuries.
• Hernon — a family found almost entirely in Connemara and the Aran Islands.
• Faherty (Ó Fathartha) — a Connacht name, clustered in south Connemara.
• Coyne (Ó Cadhain) — closely linked to the south Connemara coast.
• Forde (Mac Giolla na Naomh) — a south Galway and Clare family; English clerks mistranslated their Gaelic name as Ford.

Many of these names appear in Irish-language form in records from Connemara and the Aran Islands. A birth or marriage record from the 1800s in this area may show both the anglicized and Irish-language spelling. That dual form gives useful clues when you search it online.

How to Research Your Galway Family Name

Tracing a Galway name to its roots means working through a few layers of records. These are the best free resources available today.

The 1926 Irish Census

The 1926 Irish Census went online in April 2026 at the free census site. It records over 3 million people across Ireland. You can search by name, county, and townland. If your family left Ireland in the early 20th century, you may find grandparents listed right down to their exact townland in County Galway.

Griffith’s Valuation (1847–1864)

Griffith’s Valuation is a land survey of Ireland. It ran between 1847 and 1864. It lists the head of each house, the land size, and their landlord’s name. You can search it free at the free site. For Galway families, it shows which parishes your ancestors lived in right after the Famine. It is often the most useful snapshot of where a family stood before they left.

Catholic Parish Records

Irish Catholic registers record baptisms, marriages, and burials. In County Galway, some parishes hold records going back to 1783. You can search them free at the site, which covers over 80 Galway parishes. Civil records of births, deaths, and marriages began in 1864. These are also there.
