Halleran History, Family Crest & Coats of Arms 

Origins Available: 
  Ireland 


The name Halleran 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 Halleran family

The surname Halleran 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

Halleran migration to the United States +

Many Irish families did not fare so well within the English-ruled Ireland. Besides racial and religious discrimination, many families were renting out small tracts of farmland from absentee landowners at often unreasonable rates. Beginning in the late 18th century, moderately well off Irish families decided to emigrate to British North America or the United States in order to own their own plot of land. A radical change occurred in the 1840s, however, with the Great Potato Famine of the 1840s. Up to this point, the island's population had been increasing rapidly and a steady demand over the years for grain crops had depleted soil. Two failed crops and one poor one caused widespread disease and starvation. Thousands boarded ships looking for opportunities elsewhere. North America welcomed them as a source of cheap labor required for the many industrial and infrastructure projects underway, and as a means to quickly occupy the western regions. Research into immigration and passenger ship lists indicates that people bearing the name Halleran were among the earliest settlers to arrive in North America:
