O'Halloran History, Family Crest & Coats of Arms

Origins Available:
Ireland

The name O'Halloran originally appeared in Gaelic as Ó hAllmhurain, which is derived from the word allmhurach, which means pirate. 1

The main branch of the family claim descent through the O'Connors (Kings of Connaught) and as such from the Heremon Kings of Ireland. 2

Early Origins of the O'Halloran family

The surname O'Halloran was first found in counties of Clare and Galway (Irish: Gaillimh) part of the province of Connacht, located on the west coast of the Island, where they held a family seat from very ancient times. The Holleran variant is typical to Counties Galway and Mayo. 3

"This family were, as the name implies, 'importers' of Wine; and were lords of Clan Fergail, a district in which Galway town is situate; and had their castle at Barns, close to the sea-side, about three miles west of Galway. The MS. Vol. H. 2.17, in the Library of Trinity College, Dublin, states that 'O'Halloran is the chief of twenty-four townlands on Clan Fergail; and of theses are the O'Antuiles and O'Fergus of Roscam.' That statement refers to the twelve century. These twenty-four townlands of Clan Fergail lay east of the river Gallimh (or 'Galway.') In the 13th century the O'Hallorans were dispossessed of their ancient inheritance of Clan Fergail by the De Burgos [(Burke)] invaders. The O'Hallorans and the O'Flahertys, [moved] to Iar (or West) Connaught, where they built the castle of O'Hery in Gnomore; and according to tradition, the castle or Rinville in Northern Connenara. According to the Chronicles of the Wars of Thomond, at A.D. 1309, there was another family of the O'Hallorans in Thomond, descended from the stock of the O'Briens and other Dalcassians in Munster." 2

O'Halloran migration to the United States +

Irish emigration to North America began modestly in the late 18th century. At this time, Irish families made the journey to British North America and the United States by choice and after careful consideration: they were primarily in search of a suitably large stretch of land to call their own. This pattern would change most dramatically during the Great Potato Famine of the late 1840s. For example, the years 1825-1845 saw approximately 450,000 heading to British North America and 400,000 to the United States, but in 1847, at the height of the famine, it is estimated that more than 104,000 Irish immigrants went to British North America and more than 119,000 to the United States. An examination of passenger and immigration lists has revealed many early immigrants bearing the name O'Halloran:
