Houlihan Name Meaning
 Irish: Anglicized form of Gaelic Ó hUallacháin ‘descendant of Uallachán’, a personal name from a diminutive of úallach ‘proud’, ‘arrogant’.

Source: Dictionary of American Family Names ©2013, Oxford University Press


*The surname Hoolihan has been spelled many many different ways over the centuries with countless variations and misspellings. The main causes are translation from Irish to English, Anglicization, Typo, etc. *

Here is what Woulfe had in his 1923 book:

"Ó hUALLACHÁIN—I—O Huolighane, O Holeghane, O Holohan, O'Houlihan, Houlihan, Hoolihan, Holohan, (Holland, Nolan), &c.; 'descendant of Uallachán' (diminutive of uallach, proud); the name of several distinct families, the best known being those of Offaly and Thomond. The name was also very common in West Cork, where it is now often anglicised Holland; also common in Mayo and Roscommon, where it is anglicised Nolan"


The Book Of IRISH FAMILIES Great and Small:

There were at least two separate families who formed the origins of the Houlihan surname in Ireland. The name is found more anciently spelled as O hUallachain, and the family is found in Counties Offaly (Kings) and Clare, denoting two separate 'clans'.

In Offaly, the Houlihans served as chiefs of Clan Colgan alongside the O'Hennessys.

Keatings History gives "O'Huallachain, or O'Hoolaghan", sometimes Anglicized as O'Coulaghan and Mac Conlaghan, to show a few of the many different spellings of the name. They were given by O'Dugan to be chiefs of Siol Anmachadha.

Branches of these Houlihan families have spread southwards independently, so that many of the name are found in Co. Cork.

In the 17th century both Hologhane and Hologhon were found as principal names of Kilkenny, showing two more variants of the name. Other spellings include Oulihan, Hoolahan, Whoolahan and Holoughan to name but a few.

By the 1890's Houlihan was recorded in Kerry, Limerick, Cork, and Clare. "Holohan" was found in Kilkenny at that time.

William Oullahan was a merchant in Dublin, (1781), and from his line, John in 1877 was living in Baltimore, MD.. The firm "Oullahan and Co." miners, in Stockton, California, stems from this line also. Family members were noted in O'Hart as having settled in New York and Washington D.C. As well."

O'Laughlin, Michael C. The Book Of IRISH FAMILIES Great and Small. Kansas City: Irish Genealogical Foundation, 1997. Print.ohn O'Hart has three Lineages for Ó hUallacháin in his book "Irish Pedigrees; or, The Origin and Stem of the Irish Nation" "Entered according to Act of Congress, by RICHARD OULAHAN in the year 1888, In the Office of the Librarian of Congress, at Washington.



From an unknown newspaper clipping: 

"Hoolahan or Wholihan (in reply to M. Wholihan. Willesden. London) was the surname of many distinct families the best-known of which were those of Offaly and Thomond. When the Thomond family were dispossessed of their territory which extended into Connacht they dispersed and settled in counties Dublin, Galway, Kildare, Kilkenny, Offaly, Meath, Mayo, and Westmeath. They assumed anglicised names such as Colaghan, Coolacan, Hulahan, Halegan, Halligan, Holahan, Hoolahan, Howlan, Olehan, Oulahan, Woolahan, Merry, Proud, Whelton and Wilton. Thomas Nolan O H-Uallachan of Ballinrobe was in 1616 the first to be granted a license to keep taverns and sell wines and spirits in Connacht."


From Surnamedb.com:

Last name: Houlahan

This is a famous Irish surname of great antiquity. It is recorded in at least seventeen spellings including: Houlaghan, Hoolohan, Holohan, Holian, Houlahan, Houlihan, Hanalan, Oolahan, Woolaghan, Whoolehan and even sometimes in County Clare as Holland, in Roscommon as Nolan, and in Kilkenny as Merry! However spelt the origination is the pre 10th century Gaelic O' hUallachain, which translates as the male descendant of Uallachan, a personal name meaning proud and arrogant. Two distinct septs of this name arose in Ireland, one in County Offaly and the other in Thomond, an ancient territory comprising most of County Clare with adjacent parts of Counties Limerick and Tipperary. In due course the septs spread southwards, and several members of the sept today residing in Munster spell their name Houlihan, Holland or Nolan, the latter two forms resulting from confusion over the original Gaelic form of the name in 17th Century records. In the 1659 census the majority of namebearers were recorded in County Kilkenny where Holohan is the most usual present day spelling, although synonymously with Merry. In a pardon of 1558 one, Richard Merry, alias O'Howloughane, was recorded in County Kilkenny. The first recorded spelling of the family name is shown to be that of Donal O'Hoolahan, the Archbishop of Cashel. This was dated 1171, in the "Ecclesiastical Records of County Tipperary", during the reign of King Rory O'Conor, last native High King of Ireland, 1166 - 1175. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
