The emergence of Travellers as a distinct group occurred long before the Great Famine, a genetic analysis shows.

The Plantation of Ulster began around that time, with native Irish displaced from the land, perhaps to form a nomadic population.

argues against this view, saying that there is no archaeological or placename evidence for a migration or a takeover by a small group of elites.

than in the rest of Ireland; furthermore, "Ó" surnames are less common in Scotland having been brought to Scotland from Ireland. The proper surname for a woman in Irish uses the feminine prefix nic (meaning daughter) in place of mac. Thus a boy may be called Mac Domhnaill whereas his sister would be called Nic Dhomhnaill or Ní Dhomhnaill – the insertion of 'h' follows the female prefix in the case of most consonants (bar H, L, N, R, & T). A son has the same surname as his father. A female's surname replaces Ó with Ní (reduced from Iníon Uí – "daughter of the grandson of") and Mac with Nic (reduced from Iníon Mhic – "daughter of the son of"); in both cases the following name undergoes lenition. However, if the second part of the surname begins with the letter C or G, it is not lenited after Nic. Thus the daughter of a man named Ó Maolagáin has the surname ''Ní Mhaolagáin'' and the daughter of a man named Mac Gearailt has the surname ''Nic Gearailt''. When anglicised, the name can remain O' or Mac, regardless of gender. There are a number of Irish surnames derived from Norse personal names, including

The Mac Lochlainn, Ó Maol Seachlainn, Ó Maol Seachnaill, Ó Conchobhair, Mac Loughlin and Mac Diarmada families, all distinct, are now all subsumed together as MacLoughlin. The full surname usually indicated which family was in question, something that has been diminished with the loss of prefixes such as Ó and Mac. Different branches of a family with the same surname sometimes used distinguishing epithets, which sometimes became surnames in their own right. Hence the chief of the clan Ó Cearnaigh (Kearney) was referred to as An Sionnach (Fox), which his descendants use to this day. Similar surnames are often found in Scotland for many reasons, such as the use of a common language and mass Irish migration to Scotland in the late 19th and early to mid-20th centuries.

Social mobility was usually downwards, due to social and economic pressures. The ruling clan's "expansion from the top downwards" was constantly displacing commoners and forcing them into the margins of society. As a clan-based society,

Irish identity

Thomas Davis (Young Irelander), Thomas Davis, a prominent Protestant Irish nationalists, Protestant Irish nationalist and founder of the Irish nationalist Young Ireland movement, identified the Irish as a Celtic nation. He estimated that ethnically, 5/6ths of the nation were either of Gaelic Irish-origin, or descended from returned Scottish Gaels (including much of the Ulster Scots people, Ulster Scots) and some Celtic Welsh (such as his own ancestors and those carrying surnames such as Walsh and Griffiths). As part of this he was a staunch supporter of the Irish language as the "national language". In regards to the Germanic minority in Ireland (of Norman and Anglo-Saxon origin) he believed that they could be assimilated into Irishness if they had a "willingness to be part of the Irish Nation".

Irish diaspora

The Irish diaspora consists of Irish emigration, emigrants and their descendants in country, countries such as the United States, Great Britain, Canada, Australia, New Zealand, South Africa, and nations of the Caribbean such as Jamaica and Barbados. These countries all have large minorities of Irish descent, who in addition form the core of the Catholic Church in those countries. Many famous and influential figures have claimed Irish ancestry such as Che Guevara, Walt Disney, Barack Obama, John F. Kennedy, JFK, Muhammad Ali and ''Marshal of France, Maréchal'' Patrice de MacMahon, Duke of Magenta, The 1st Duke of Magenta, the second President of the French Republic, President of the Third Republic of France, Third Republic. Many Irish people were also transported to the island of Montserrat, to work as indentured servants, exiled prisoners or slaves.

following the Irish Confederate Wars. The African slave population on the island attempted a rebellion against the Irish plantation owners on 17 March 1768. The date was chosen with the idea that the plantation owners would be distracted by St. Patrick's day festivities, but the plot was ultimately discovered and several of those involved were put to death. To this day, the Island celebrates St. Patrick's Day as a public holiday to commemorate the revolt and honour those who lost their lives. People of Irish descent also feature strongly in Latin America, especially in Argentina and important minorities in Brazil, Chile, and Mexico. In 1995, President Mary Robinson reached out to the "70 million people worldwide who can claim Irish descent". Today the diaspora is believed to contain an estimated 80 million people.The island history

There are also large Irish communities in some mainland European countries, notably in Spain, France and Germany.

. In the early years of the English Civil War, a French traveller remarked that the Irish "are better soldiers abroad than at home". Later, Irish brigades in France and Spain would fight in the War of the Spanish Succession, Wars of the Spanish and War of the Austrian Succession, Austrian Succession and the Napoleonic Wars. In the words of Field Marshal (United Kingdom), Field Marshal Arthur Wellesley, 1st Duke of Wellington, The 1st Duke of Wellington, the Irish-born 'Iron Duke', a notable representative of the Irish military diaspora, "Ireland was an inexhaustible nursery for the finest soldiers". The British Legions were units that Military career of Simón Bolívar, fought under Simón Bolívar against Spain for the independence of Colombia, Venezuela, Ecuador, and Peru.

as a result of the famine. For both the Irish in Ireland and those in the resulting Irish diaspora, diaspora, the famine entered folk memory and became a rallying point for various Irish nationalism, nationalist movements. There are Afro-Caribbean people descended from Irish Caribbean, Irish immigrants in the Caribbean, especially on Barbados, Jamaica, and Montserrat. They often have Irish surnames, speak a form of Caribbean English influenced by the Irish vernacular and, in some cases, sing Irish songs. People of Irish descent are the second largest self-reported ethnic group in the United States, after German Americans. Nine of the signatories of the American Declaration of Independence were of Irish origin. Among them was the sole Catholic signatory, Charles Carroll of Carrollton, whose family were the descendants of Ely O'Carroll, an Irish prince who had suffered under Cromwell. At least twenty-five President of the United States, presidents of the United States have some Irish ancestral origins, including George Washington. Since John F. Kennedy took office in 1961, every American President (with the exception of Gerald Ford and Donald Trump) has had some Irish blood. An Irish-American, James Hoban, was the designer of the White House. John Barry (naval officer), Commodore John Barry, who was born in County Wexford, was the "Father of the United States Navy". In the mid-19th century, large numbers of Irish immigrants were conscripted into Irish regiments of the United States Army at the time of the Mexican–American War. The vast majority of the 4,811 Irish-born soldiers served in the U.S. Army, but some deserted to the Mexican Army, primarily to escape mistreatment by Protestant officers and the strong anti-Catholic discrimination in America. These were the ''San Patricios'', or Saint Patrick's Battalion—a group of Irish led by Galway-born John O'Riley, with some Roman Catholicism in Germany, German, Roman Catholicism in Scotland, Scottish and Roman Catholicism in the United States, American Catholics. They fought until their surrender at the decisive Battle of Churubusco, and were executed outside Mexico City by the American government on 13 September 1847. The battalion is commemorated in Mexico each year on 12 September. During the 18th and 19th centuries, 300,000 free emigrants and 45,000 convicts left Ireland to settle in Australia. Today, Australians of Irish descent are one of the largest self-reported ethnic groups in Australia, after English and Australian. In the 2006 Australian Census, Census, 1,803,741 residents identified themselves as having Irish ancestry either alone or in combination with another ancestry. However this figure does not include Australians with an Irish background who chose to nominate themselves as 'Australian' or other ancestries. The Australian embassy in Dublin states that up to thirty per cent of the population claim some degree of Irish ancestry. It is believed that as many as 30,000 Irish people emigrated to Argentina between the 1830s and the 1890s. This was encouraged by the clergy, as they considered a Catholic country, Argentina, preferable to a more Protestant United States. This flow of emigrants dropped sharply when assisted passage to Australia was introduced at which point the Argentine government responded with their own scheme and wrote to Irish bishops, seeking their support. However, there was little or no planning for the arrival of a large number of immigrants, no housing, no food. Many died, others made their way to the United States and other destinations, some returned to Ireland, a few remained and prospered. Thomas Croke Archbishop of Cashel, said: "I most solemnly conjure my poorer countrymen, as they value their happiness hereafter, never to set foot on the Argentine Republic however tempted to do so they may be by offers of a passage or an assurance of comfortable homes." Some notable Argentines of Irish descent and Irish people who settled in Argentina include Che Guevara, former president Edelmiro Julián Farrell, and admiral William Brown (admiral), William Brown. There are people of Irish descent all over South America, such as the Chilean liberator Bernardo O'Higgins and the Peruvian photographer Mario Testino. Although some Irish retained their surnames intact, others were assimilated into the Spanish vernacular. The last name ''O'Brien'', for example, became ''Obregón''. People of Irish descent are also one of the largest self-reported ethnic groups in Canada, after English Canadian, English, French Canadian, French and Scottish Canadians. As of 2006, Irish Canadians number around 4,354,155.
