This is a list of the longest place names in Ireland.
 It includes names written in English as a single word of at least 20 letters.
 The vast majority of English-language place names in Ireland are anglicisations of Irish language names.
 The spelling which has legal force is usually that used by the Ordnance Survey of Ireland.
 Many of Ireland's longest place names are found in the far west of the island, where the Irish language survived the longest; including Gaeltacht areas, where it is still the vernacular.
 These names are generally written as multiple words in Irish.
The vast majority of placenames in Ireland are anglicisations of Irish language names; that is, adaptations of the Irish names to English phonology and spelling.
 However, some names come directly from the English language, and a handful come from Old Norse and Scots.
 The study of placenames in Ireland unveils features of the country's history and geography, and the development of the Irish language.
 The name of Ireland itself comes from the Irish name "Éire", added to the Germanic word "land".
 In mythology, Éire was an Irish goddess of the land and of sovereignty (see Ériu).
Siobhan ( ) is a female given name of Irish origin.
 Its spelling in the Irish language is Siobhán (] or ] ), while the most common anglicisations are Shevaun and Shivaun.
McCawley and MacCawley are surnames in the English language.
 The names are Anglicisations of several Gaelic-language surnames.
 There are several etymological origins for the names: all of which originated as patronyms in several Gaelic languages—Irish and Scottish Gaelic.
 Although the English-language surnames are ultimately derived from Gaelic patronyms, the English-language surnames, and the modern Gaelic-language forms do not refer to the actual name of the bearer's father or grandfather.
 The surnames are not very common.
Jason L. McCoy is the former mayor of Vernon, Connecticut, and a trial lawyer.
 In 2009, McCoy was elected to his first term in 2007.
 McCoy was re-elected as mayor.
 He had served on the Vernon Town Council and was the deputy mayor of Vernon from 2005 to 2007.
 In 2009, McCoy was one of six mayors in Connecticut chosen by the Governor M. Jodi Rell to work closely with state officials and lawmakers to identify savings and recommend mandate relief to help close Connecticut's state budget shortfall.
 McCoy served as mayor of a municipality that holds town meetings to pass the mayor's yearly proposed municipal budget, which can then be sent to referendum for approval by privately cast ballot.
 During McCoy’s two terms (four years) as mayor of Vernon he proposed and passed four municipal budgets.
 The Town of Vernon municipal budgets during McCoy’s terms as mayor resulted in the municipal tax rate or mil rate needed to fund the municipal budget being reduced in the 2008–2009, 2009-2010 budgets, the 2010-2011 tax rate or mil rate remained the same.
 In the 2011-2012 budget the tax rate was cut which resulted in a taxes cut to the taxpayers in the Town of Vernon, Connecticut.
 The 2011–2012 budget proposal was passed and adopted at the annual town meeting as opposed to being sent to referendum.
Falvey is a surname which is an anglicisation of the name Ó Fáilbhe: in the Irish language Ó means "descendant" [of] and "fáilbhe" literally means "lively, pleasant, sprightly, merry, cheerful" or, according to another historian, "joker".
 Other anglicisations include "O’Falvie, O’Falvy, O’Failie, O’Falvey, Falvey, Fealy" and "Fealey".
 The O’Falvey’s trace their descent to Conaire, who was King of Ireland at the beginning of the Christian era.
 The O’Falvey’s are recorded to have been powerful chiefs of Corcu Duibne, specifically the Dingle Peninsula of modern-era County Kerry, the barony of Corcaguiny.
 They were also Lords of Inveragh during the tenth century, and the hereditary admirals of Desmond.
 The veracity of such claims is in their intent more than their detail, thus an "admiral" may well have been the leader of some boats, and a "lord" may have been a somewhat less imposing figure than a Victorian English nobleman.
The gallowglasses (also spelt galloglass, gallowglas or galloglas; from Irish: "gall óglaigh" meaning foreign warriors) were a class of elite mercenary warriors who were principally members of the Norse-Gaelic clans of Scotland between the mid 13th century and late 16th century.
 As Scots, they were Gaels and shared a common background and language with the Irish, but as they had intermarried with the 10th century Norse settlers of western Scotland, the Irish called them "Gall Gaeil" ("foreign Gaels").
MacGaffin and McGaffin are Northern Irish surnames.
 They are Anglicisations of the Irish language "Mac Eacháin", meaning "son of "Eachán"".
 The personal name "Eachán" is a diminutive of the personal name "Eachaidh", which is based upon the Gaelic "each", meaning "horse".
McCoy is a common surname of Scottish origin in the lands of Kintyre and then Irish (Gallowglass) origin.
 It is an Anglicisation of its Irish Gaelic form Mac Aodha, meaning "son of Aodh" (an old word for "Fire", a Celtic deity).
 It is particularly found in Ulster (Counties Antrim, Armagh and Monaghan) where many settled around the 13th century, having been Gallowglasses, and also in counties Limerick and Cork.
 Aoidh and Mac Aoigh were sometimes Anglicised as Hugh and McHugh.
Ó Maolchonaire, more properly Ó Maol Chonaire, sometimes Ó Mhaoilchonaire, Ó Maolconaire, etc., was the surname of a family of professional poets and historians in Medieval Ireland.
 Traditionally it would have been spelled without the 'h', but with a dot over the 'c', either of which indicate an aspirant.
 In a period prior to the surrender of the Ó Conchubhair Donn and the other Connacht chieftains, it was Anglicised O'Mulconry, however the family was required to drop the national prefixes as part of the terms of surrender.
 Specific families, particularly the educators were systematically targeted, as part of the plot to destroy the Irish culture and language, as well as the Catholic religion.
 This can add great confusion to researchers of this important literary and religious family.
 It is now rendered most commonly Conry, sometimes Conroy, possibly sometimes King.
 There are many distinct groups of Conroys, some of whom also, though less commonly, use Conry, which are Anglicisations of disparate Irish Gaelic names.
