Irish Surnames from Longford – Origins, Meanings & Heritage Roots

Sharing is caring!

County Longford sits at the heart of Ireland. It is small and often overlooked by tourists. But for Irish-Americans tracing their roots, it holds real depth. The county was home to the O’Farrell family — one of the great Gaelic dynasties of the Irish Midlands. They ruled the ancient territory of Annaly for centuries. Their names, and the names of the families who served them, spread across the world during the Famine years. If your surname traces to Longford, here is what you need to know.

Irish Surnames from Longford: The Land of Annaly

The ancient name for County Longford is Annaly. This comes from the Gaelic An Anghaile — the territory of the O’Farrell sept. The O’Farrells ruled this land for centuries. They were one of the most powerful Gaelic families in the Irish Midlands.

The county sits between the River Shannon to the west and low drumlin hills to the north. It is flat farming land, cut through by the Royal Canal. In Gaelic times, this landscape was covered with dense woodland and bog. It gave the native families shelter from invaders.

The Plantation of Longford in the early seventeenth century broke the old order. The O’Farrells and other Gaelic families lost their land. Their surnames survived the plantation and the Famine. Today, those names are carried by families across Ireland, Britain, America, and Australia.

O’Farrell – Ó Fearghail: Lords of Annaly

No name is more tied to County Longford than O’Farrell. The Gaelic form is Ó Fearghail — “descendant of Fearghail.” The personal name Fearghail means “man of supreme valour.” It was one of the great names of the Irish Midlands.

The O’Farrells ruled the territory of Annaly for several hundred years. Their power covered most of modern County Longford. They fought to hold their land against Norman expansion from the east. For a long time, they succeeded.

Their main stronghold was Rathcline Castle near Lanesborough on the shores of Lough Ree. They were patrons of the church and built several abbeys across their territory. The O’Farrells also kept hereditary poets who recorded their history in the Gaelic tradition.

After the Plantation of Longford in 1619, the O’Farrells lost their land. Many went into exile as soldiers in Catholic armies in Europe. The name appears in military records in France and Spain throughout the 1600s and 1700s.

Today, Farrell and O’Farrell are among the most common surnames in County Longford. In America, the name appears across Irish communities from New York to Boston. If your name is Farrell, a Longford connection is very possible.

Quinn – Ó Cuinn: A Midlands Name

Quinn is one of the most common surnames in Ireland. In County Longford, it has a strong native presence. The Gaelic form is Ó Cuinn — “descendant of Conn.” The personal name Conn was widely used in early Ireland. It means “sense,” “reason,” or “wisdom.”

The Quinn sept was well established across the Irish Midlands. In Longford, the name is found throughout the county. It spread widely during the Famine emigration of the 1840s. In America, Quinn is found in Irish communities across the east coast and the Midwest.

Mulvihill – Ó Maolmhichíl: A Longford Original

Mulvihill is a surname closely tied to County Longford. The Gaelic form is Ó Maolmhichíl — “descendant of the devotee of St. Michael.” The prefix maol means devotee or servant. It was combined with the name of the archangel Michael. This was common in early Irish naming, reflecting deep Catholic devotion.

The Mulvihill sept was native to County Longford. This is one of the surnames most strongly linked to the county. After the Plantation, the name spread south and west. Today it is common in Longford, Roscommon, and along the western seaboard.

In America, Mulvihill arrived with the Famine emigration. The name is found in Irish communities in New York and across the Midwest.

Egan – Mac Aodhagáin: The Hereditary Lawyers

Egan is a name with a fascinating story. The Gaelic form is Mac Aodhagáin — “son of Aodhagán.” Aodhagán is a form of Aodh, an old Irish name meaning “fire.” The name Egan was well established across the Irish Midlands.

The Mac Aodhagáin family held a specific role in Gaelic Ireland. They were hereditary lawyers — a brehon family who interpreted the ancient Irish legal code. This knowledge passed from father to son across generations. In Gaelic society, their skill gave them high status.

The Brehon Laws were a distinct Irish legal system that pre-dated the English conquest by centuries. The Egans were among the families who kept this tradition alive. After the English conquest, the Brehon Laws were abolished. The Egan family lost their special role.

Today, Egan is common across Longford, Offaly, and Tipperary. In America, the name is found in Irish communities along the east coast.

Goldrick – Mac Ualghairg: A Longford Original

Goldrick is a rare and interesting surname. It comes from the Gaelic Mac Ualghairg, meaning “son of the proud and fierce one.” Over time, this was anglicised to Goldrick. Variants include Goodrick and Guildrick, though Goldrick is the most common form today.

The Goldrick family was native to County Longford. This is one of the surnames most specific to the county. It stayed concentrated in Longford through the centuries. It did not spread as widely as other Midlands names.

If your family name is Goldrick, a County Longford origin is almost certain.

Mulligan – Ó Maolagáin: Common Across Longford

Mulligan is a well-known Irish surname. The Gaelic form is Ó Maolagáin — “descendant of Maolagán.” The prefix maol suggests a servant or devotee. The full personal name’s exact meaning is uncertain.

The Mulligan sept was based in the Irish Midlands. In Longford and neighbouring counties, the name is common. It spread across the country during the Famine years. In America, Mulligan is found in Irish communities from Boston to Chicago.

McKeon – Mac Eoghain: Descendants of Eoghan

McKeon comes from the Gaelic Mac Eoghain — “son of Eoghan.” The personal name Eoghan (also written Owen or Eugene in English) was one of the most popular names in early Ireland. It means “born of the yew tree” or “well-born.”

The McKeon family was well established in County Longford and neighbouring Roscommon. The name takes many forms. MacKeon, Keown, and Owen are all anglicisations of the same Gaelic root.

In America, the name often appears as Keon or McKeon. It is found in Irish communities on the east coast, particularly in New York and Boston.

How Longford Surnames Crossed the Atlantic

County Longford was badly hit by the Great Famine of 1845 to 1852. The county lost a large share of its population to death and emigration. Catholic families — O’Farrells, Quinns, Mulvihills, Egans — left through the ports of Dublin and Drogheda. They arrived in New York, Boston, and Philadelphia. Many settled in the Irish working-class communities of those cities.

Their descendants now number in the millions. Longford is a small county. But its surnames are spread across the English-speaking world.
