Dalton Irish Surname: History, Origins & Heritage of a Hiberno-Norman Family

Dalton family woven blanket with the Dalton family crest on the Irish National Tartan, honoring the Hiberno-Norman Daltons of Westmeath

Dalton is a Hiberno-Norman surname of County Westmeath. It came to Ireland as the Anglo-Norman de Daltune, “of Dalton,” is written Daltún in Irish, and the family’s lands in the west of Meath were known as Dalton’s country before they became the barony of Rathconrath. To see the name on blankets, a mug, a flag and an ornament, visit the Dalton Irish family heritage gifts collection.

Quick answer: Rev. Patrick Woulfe gives the Irish forms Dalatún and Daltún and the English forms Dalton and D’Alton. He explains the name as “of Dalton,” a common place-name in the north of England, and adds that it might instead come from “de Aletone,” of Alton. Robert and William de Daltune appear on the roll of the Dublin guild merchant in 1226. The family went on to hold Rathconrath in County Westmeath and lost their estates in the Cromwellian and Williamite confiscations.

What Does the Dalton Surname Mean?

Dalton is a place-name surname. In his Irish Names and Surnames, Woulfe traces it to the Norman form de Daltune, “of Dalton,” after one of the several villages of that name in northern England. English place-name scholars explain Dalton from the Old English dæl, valley, and tūn, farmstead, so the Cumbrian Dalton, for example, is a “valley farmstead.”

Woulfe also leaves room for a second source, “de Aletone,” meaning of Alton. Alton is a different English place-name, and the “valley” meaning belongs to Dalton alone. Whichever village the first bearer left, the family were known in Ireland as de Daltune, later D’Alton and Dalton, and the Irish speakers around them rendered the name Daltún.

From the Dublin Guild to Dalton’s Country

The earliest Irish record Woulfe cites is urban, not rural. Robert de Daltune and William de Daltune were admitted to the Dublin guild merchant in 1226, less than sixty years after the first Anglo-Norman landings. The family’s lasting home, however, was in the midland lordship of Meath.

By the early sixteenth century a stretch of western Meath carried the family name. When the Irish parliament divided Meath in 1543 and created the shire of Westmeath, four districts named for their Norman lords were turned into baronies: Dillon’s country became Kilkenny West, Tyrrell’s country became Fartullagh, Delamare’s country became Rossaughe, and Dalton’s country became Rathconrath. On logainm.ie, Ireland’s national placenames database, Rathconrath is Ráth Conarta, from ráth, a ring-fort, and it names both a civil parish and the barony around it.

From Forfeiture to Mount Dalton

Woulfe records that the Daltons held Rathconrath until the Cromwellian and Williamite confiscations, when their estates were forfeited.

One branch came back. According to the National Inventory of Architectural Heritage, Count Richard D’Alton built Mount Dalton House in 1784, after a distinguished career in Austrian service, in the townland of Loughan. The house was home to Count Oliver D’Alton, who died in 1799, and later to Countess Elizabeth Begg, née D’Alton, who died in 1832. The lake beside it is still listed on logainm.ie as Mount Dalton Lough, An Lochán, in the barony of Rathconrath, a place-name that keeps the family in the landscape of Dalton’s country.

Dalton, D’Alton and Daton: Telling the Names Apart

Dalton and D’Alton are the same Irish name, and both spellings run through the records side by side; the historian John D’Alton and Cardinal D’Alton kept the older form. Search both, along with de Daltune in medieval sources.

Kilkenny needs care. Woulfe notes that the old Kilkenny family of Daton, Dátún, from Autun in Normandy, was “sometimes incorrectly re-anglicised Dalton.” A Kilkenny Dalton may therefore belong to the Daton line rather than to the Westmeath family. Dalton is also a common surname in England, where it grew separately from the English villages of the name, so an emigrant family’s own parish and townland records decide which Dalton story is theirs.

How Can I Research Dalton Family History?

  • IrishGenealogy.ie: search the official state indexes of Irish births, marriages and deaths at no cost, beginning with a Westmeath Dalton born after 1864.
  • National Archives census of 1901 and 1911: search Dalton and D’Alton households in Westmeath, then widen to Longford, Meath and Offaly.
  • Griffith’s Valuation: the land survey of the mid-nineteenth century, which places a tenant in a named townland such as Loughan or Rathconrath.
  • National Library of Ireland parish registers: Catholic baptism and marriage entries for Westmeath, many from before state registration began in 1864.
  • logainm.ie: the parish and barony of Rathconrath, their townlands and their historical spellings.

Check the Daton spelling too if a family came from Kilkenny, and look for de Daltune and D’Alton in older documents.
