The Nolan surname derives from the Irish Ó Nualláin, meaning descendant of Nuallán — a personal name built on the Old Irish nuall, meaning famous, renowned, or eminent, a quality that spoke to an ancestor of recognised public standing in the Gaelic community. The O'Nolans were a sept of genuine consequence in the medieval political landscape of County Carlow, one of the smaller but historically tenacious Gaelic dynasties of southeastern Ireland who maintained their territorial authority in the barony of Forth across several centuries of Norman encroachment. Nolan, O'Nolan, and the older Ó Nualláin are all found in records, with Nolan the dominant form today. For anyone researching Irish ancestry under this surname, County Carlow is the starting point in the overwhelming majority of cases.
Quick answer: Nolan is the anglicised Ó Nualláin, "descendant of the renowned one," the lords of Forth O'Nolan in County Carlow — a sept said to have held the hereditary right of inaugurating the kings of Leinster. Their motto was Buaidh nó Bás, "Victory or Death," and the name remains most characteristic of Carlow to this day.
What Is the Meaning Behind the Nolan Name?
The personal name Nuallán carried genuine prestige in the early Irish tradition — a name built on renown rather than on martial prowess or territorial authority, suggesting an ancestor whose reputation was established through some quality that the community recognised and remembered. The root nuall also carried the sense of a shout or proclamation, fitting for a family linked to public acclamation. Hereditary surnames became widespread in Ireland from the ninth and tenth centuries, among the earliest in western Europe, and the O'Nolan family were among those who established a distinct dynastic identity in the southeast during this formative period. The O' prefix, gradually dropped under centuries of English administration, is restored in more formal genealogical usage where the Gaelic connection is made explicit; Nowlan and Knowlan are also found as variant spellings.
Where Were the O'Nolans in County Carlow?
The O'Nolans were lords of Fotharta Fea — Forth O'Nolan, a territory in the barony of Forth in the south of County Carlow — and as chieftains of this landscape they exercised local authority, collected tribute from subordinate families, and participated in the complex web of alliances and conflicts that characterised Gaelic political life in Leinster. They held a particularly distinguished ceremonial role: the O'Nolan chiefs were said to possess the hereditary right of inaugurating the MacMurrough kings of Leinster, a mark of standing far beyond the size of their territory. County Carlow in the medieval period was a contested frontier zone between the expanding world of the Anglo-Norman Pale and the Gaelic territories of the Leinster highlands, and the O'Nolans, like their neighbours the MacMurrough Kavanaghs, were subject to sustained pressure from Norman settlement while maintaining significant local authority for considerably longer than many smaller Leinster families.
The motto associated with the Nolan family in Irish genealogical sources is Buaidh nó Bás — Victory or Death — one of the most direct and uncompromising of the traditional Irish family mottos, a binary that speaks to the warrior culture of Gaelic Ireland and to the particular circumstances of a sept that maintained its Gaelic identity against sustained external pressure. As with all Irish surnames, any heraldic arms associated with the Nolan name were granted to specific individuals and branches rather than to the surname as a whole.

Who Was Paddy Nolan and What Did He Achieve?
Among the Irish diaspora figures who carried the Nolan name to distinction abroad, Paddy Nolan KC stands out as one of the more remarkable. Born Patrick James Nolan in County Tipperary in 1858, he emigrated to Canada and built a legal career in Calgary during the frontier era of the 1880s and 1890s that made him the most celebrated defence barrister in the Northwest Territories. Known as Paddy the Prince, Nolan was renowned across western Canada for his courtroom theatrics, his command of the jury, and his particular gift for defending cattle thieves, whisky traders, and clients the frontier legal system was inclined to convict on sight. His Irish wit, his Catholic faith, and his instinct for the underdog made him a legendary figure in a period of Canadian history that rarely celebrated Irish Catholic immigrants.
How Did the Plantation Era Affect the O'Nolan Family?
The Tudor conquest of Ireland brought sustained pressure to bear on Gaelic families across Leinster from the mid-sixteenth century onward. The Nine Years War of 1593 to 1603 and its aftermath, followed by the Cromwellian land settlements of the 1650s, resulted in the large-scale dispossession of Catholic landowning families across the province, and the O'Nolans of Carlow lost their hereditary estates through these successive waves of confiscation. Despite dispossession, the Nolan name remained strongly rooted in County Carlow through the eighteenth and nineteenth centuries, as confirmed by the Tithe Applotment Books and the Griffith's Valuation of the 1840s and 1850s.
County Carlow was affected by the Great Famine of the 1840s, and Nolan families emigrated in significant numbers to Britain, the United States, Canada, and Australia during and after those years. The Kavanagh family, the great MacMurrough dynasty of Leinster whose kings the O'Nolans inaugurated, provides the essential dynastic context for this family's medieval story. The Byrne family of Wicklow and the Leinster borderlands were among the nearest great Gaelic neighbours of the Carlow Nolans, their shared experience of survival through plantation and penal law running in parallel across two counties. The Brennan family of nearby Kilkenny and Carlow shared the same layered Leinster world under the Kavanagh overkings.
Where Is the Nolan Name Found Today?
Within Ireland the Nolan surname remains most concentrated in County Carlow, where it is one of the most characteristic local names. The name is found throughout Leinster and across the island in significant numbers, and the diaspora spread it to every corner of the English-speaking world. For ancestry researchers, the civil registration records from 1864, the 1901 and 1911 census returns for Carlow and Kilkenny, and the Griffith's Valuation are the essential starting tools.
Fun Facts About the Nolan Name
For all their small territory, the O'Nolans claimed one of the grandest ceremonial rights in Gaelic Ireland — the hereditary privilege of inaugurating the kings of Leinster, a kingmaker's role that outranked many a larger lordship. The motto Buaidh nó Bás, "Victory or Death," is among the most uncompromising in the Irish tradition. Brian O'Nolan of Strabane wrote as Flann O'Brien and Myles na gCopaleen, one of the comic geniuses of twentieth-century literature — the renowned name living up to itself. And in Canada, "Paddy the Prince" Nolan became the most famous courtroom advocate of the old Northwest, a Tipperary Nolan who made the frontier laugh and acquit.
