Quick answer: Daly is an Irish surname derived from Ó Dálaigh, “descendant of Dálach.” Patrick Woulfe glossed Dálach as a name connected with holding or attending assemblies. His surname study places the early family in Corca Adain in present-day County Westmeath and records later Ó Dálaigh branches as celebrated professional poets in several parts of Ireland.

What does the Daly surname mean?
The Irish form is Ó Dálaigh. The prefix Ó indicates descent, while Dálach is the ancestral personal name. Woulfe lists O’Daly, Daly and Dawley among English forms of the surname. Modern records also contain spellings such as Daley, and searching every form turns up relatives a single spelling would miss.
Dálach is built on dáil, “assembly,” so the ancestral name shares its root with Dáil Éireann, the Irish parliament. John Grenham notes the same connection in his account of the surname, and Woulfe traces the family’s descent to Maine, son of Niall of the Nine Hostages.
Where were the Ó Dálaigh families established?
Woulfe records the early family as chiefs of Corca Adain in what is now County Westmeath. From that midlands base, learned branches spread widely. A branch associated with Donnchadh Mór Ó Dálaigh settled at Finavarra in the Burren, County Clare, and the Galway Dalys were connected with that line. Another branch settled in Desmond and served the MacCarthy lords as professional poets. Woulfe also records branches serving the O’Reillys in Cavan, the O’Neills in Ulster and the O’Connors in Connacht.
These regional branches explain why Daly research can lead to Westmeath, Clare, Galway, Cork, Cavan and other counties. West Cork became a lasting stronghold, especially Muintir Bháire on the Sheep’s Head peninsula.
Why is the name associated with Irish poetry?
The Ó Dálaigh became one of Ireland’s best-known learned families. Woulfe names Cúchonnacht na Scoile, who died at Clonard in 1139, as the ancestor of all the bardic families of the name, and he quotes John O’Donovan that poetry then became a profession in the family, with Corca Adain sending poetic teachers to different parts of Ireland. Their work belonged to the trained Gaelic literary tradition, in which professional poets served regional patrons and preserved praise poetry, genealogy and learned culture.
Donnchadh Mór Ó Dálaigh and Muireadhach Albanach Ó Dálaigh are among the medieval poets associated with the name. Their surviving poetry and biographies illuminate the wider learned tradition of the Ó Dálaigh families.
Are Daly, O’Daly and Daley the same surname?
Yes. Daly and O’Daly are both English forms of Ó Dálaigh, as is Dawley, and Daley is a later spelling of the same name. Dates, places, occupations and relatives connect variant spellings across records.
