The Irish people are an ethnic group who originate in Ireland, an island in northwestern Europe. Ireland has been populated for around 9,000 years. The Irish people's earliest ancestors are recorded in legends – they are claimed to be descended from groups such as the Nemedians, Fomorians, Fir Bolg, Tuatha Dé Danann and the Milesians. Lebor Gabála Érenn, a book of Irish mythology tells that Milesians were Scythian descendants. The main groups that interacted with the Irish in the Middle Ages include the Picts, Scots, and the Vikings. Due to this contact, Icelanders are noted for having some Irish descent. The Anglo-Norman invasion of the High Middle Ages, the English plantations and the subsequent English rule of the country introduced the Normans and Flemish into Ireland. Welsh, Picts, Bretons, and small parties of Gauls and even Anglo-Saxons are known in Ireland from much earlier times. There have been many notable Irish people throughout history. The 6th century Irish monk and missionary Columbanus is regarded as one of the "fathers of Europe", followed by Kilian of Würzburg and Vergilius of Salzburg. The scientist Robert Boyle is considered the "father of chemistry". Famous Irish explorers include Brendan the Navigator, Robert McClure, Ernest Shackleton and Tom Crean. By some accounts, the first European child born in North America had Irish descent on both sides; and an Irishman was the first European to set foot on American soil in Columbus' expedition of 1492.
