Irish Surnames from Westmeath: The Kingdom of Meath
The ancient kingdom of Meath was one of the five provinces of early Ireland. It covered a wide stretch of the midlands. Modern Westmeath and Meath both fall within its old boundaries.
The O’Melaghlin dynasty ruled here for centuries. They were the southern branch of the Uí Néill, one of Ireland’s most powerful royal lines. For generations, they rivalled the great Brian Boru for the high kingship of all Ireland.
The Normans arrived in 1169. They changed the landscape of power fast. The de Nugent and de Dalton families took land in Westmeath. Both families became thoroughly Gaelicised within a few generations. Their surnames stayed. Their English roots faded.
Westmeath is also a county of water. Lough Ree and Lough Derravaragh are its great lakes. The River Shannon runs along its western edge. Water shaped who lived here and how they defended their territory.

O’Melaghlin – Ó Maoilsheachlainn: The High Kings of the Midlands
No family shaped Westmeath more than the O’Melachlins. The Gaelic form is Ó Maoilsheachlainn — descendant of the devotee of Saint Seachlainn. Seachlainn was an early Irish bishop and a disciple of Saint Patrick.
The family produced two High Kings of Ireland. Máel Sechnaill mac Máele Ruanaid ruled from 846 to 862. His descendant Malachy II held the high kingship twice. He reigned from 980 to 1002 and again from 1014 to 1022. Malachy II defeated the Norse at the Battle of Tara in 980. He was one of the most powerful kings in Irish history.
The Norman invasion broke the O’Melaghlin grip on Meath. The family lost most of their land but kept a presence in Westmeath for several centuries. Their name survived in different forms. McLoughlin, Loughlin, and Melaghlin are all variants of the same Westmeath royal line.
Today McLoughlin is one of the most common surnames in Westmeath and the Irish midlands. Millions of Americans, Australians, and Canadians carry this name. Many do not know they descend from the High Kings of Meath.
Daly – Ó Dálaigh: Ireland’s Greatest Poets
Daly is one of the most widespread surnames in Ireland. Its roots lie in the midlands. The Gaelic form is Ó Dálaigh — descendant of Dálach. The name Dálach comes from a word meaning one who attends assemblies. It described a public speaker or counsellor.
The Ó Dálaigh were Ireland’s hereditary poets. They served as ollamhain — chief poets — to the kings of Fir Ceall. Fir Ceall was an ancient territory covering much of modern Westmeath and Offaly. Their role was to compose praise poetry, record genealogies, and keep the memory of ruling families alive.
The Daly family spread across Ireland over the centuries. Different branches served different lords in different provinces. The name is now found in every county on the island and across the Irish diaspora worldwide.
If your name is Daly and your family traces back to the midlands, you may carry the line of Ireland’s great literary tradition.
Nugent – de Nugent: Norman Lords of Delvin
Nugent is the most distinctly Westmeath surname among the Norman families. The name comes from Nogent, a place in Normandy, France. The de Nugent family came to Ireland with the Norman invasion in the late twelfth century.
They were granted the barony of Delvin in County Westmeath. This became the heart of Nugent territory for five hundred years. The family became Barons of Delvin. In 1621, Christopher Nugent became the 1st Earl of Westmeath. The county title itself bears the mark of this family.
The Nugents became thoroughly Irish over time. They remained Catholic through the Penal era. Some went into exile in Europe as soldiers. Others stayed on reduced lands in Westmeath.
Today Nugent is concentrated in Westmeath and Meath. It is one of the clearest Norman surnames that still points directly back to its county of origin.

Mageoghegan – Mac Eochagáin: Lords of Cenél Fhiachach
Mageoghegan is one of the most distinctly Westmeath Gaelic surnames. The Gaelic form is Mac Eochagáin — son of Eochaidh. The personal name Eochaidh means horseman. It was one of the most popular names in early medieval Ireland.
The Mac Eochagáin sept ruled Cenél Fhiachach, a territory in central County Westmeath. Their seat was at Moycashel. They held this land for centuries before the Plantation broke the old Gaelic order.
The most famous member of this family is Connell Mageoghegan. He was born around 1572. In 1627, he translated the Annals of Clonmacnoise from Irish into English. This was one of the most important works of Irish historical scholarship in the seventeenth century. Without Connell Mageoghegan, much of what we know about early Ireland would have been lost.
The name today appears in several forms. Mageoghegan, Geoghegan, and Geegan are all variants of the same Westmeath sept. It remains one of the most localised Irish surnames.
Dalton – de Dalton: Settlers Who Became Irish
Dalton came to Ireland from England with the Norman invasion. The family name comes from the manor of D’Alton in Northamptonshire. They were granted lands in County Westmeath in the late twelfth century.
The Daltons settled around the Mullingar area. Over generations, they adopted Irish customs and the Irish language. Like the Nugents, they became what old writers called more Irish than the Irish themselves.
Dalton families left Westmeath in large numbers during the Famine of the 1840s. They settled in New York, Boston, and Chicago. The name is common in the Irish-American communities of those cities today.
Tyrrell – de Tirel: The Norman Military Family
The Tyrrell family came to Westmeath with Hugh de Lacy in 1172. They were granted lands in the barony of Fertullagh in the south of the county. For centuries, the Tyrrells were one of the most powerful Norman families in Westmeath.
They kept their military identity through the generations. Richard Tyrrell was a notable Irish commander in the Nine Years’ War at the end of the sixteenth century. He fought alongside Hugh O’Neill against English rule.
Like many Westmeath Norman families, the Tyrrells became Gaelicised. They married into Irish families and adopted the Irish language. After the Williamite Wars, some went into exile in Europe as Wild Geese officers.
Today Tyrrell is found mainly in Westmeath, Meath, and Kildare. The name points directly to a Norman Westmeath root.
How Westmeath Surnames Crossed the Atlantic
County Westmeath sits in the midlands, away from the main emigration ports. But its people left in large numbers, especially during the Great Famine of 1845 to 1852.
Most left through Dublin or Drogheda. They crossed to Liverpool and boarded ships for New York or Boston. Dalton, Nugent, and Geoghegan families all appear in early records of Irish communities in American cities.
An earlier wave left after the Williamite Wars at the end of the seventeenth century. Westmeath Catholic families — Nugents, Tyrrells, Daltons — joined the Flight of the Wild Geese. They served as soldiers in the armies of France, Spain, and Austria. Several Westmeath officers rose to senior rank in European service.
Their descendants now number in the millions. Westmeath is a small county. But its surnames are spread across the English-speaking world.
