There are many Irish surnames being used today in forms that are quite different than their original, ancient forms. McClaughlin originally appeared in Gaelic as Mac Lochlainn or Ó Maoilsheachlainn. The first name is derived from a Norse personal name, while the second name originally designated a follower of St. Secundinus.

Early Origins of the McClaughlin family

The surname McClaughlin was first found in County Meath (Irish: An Mhí) anciently part of the kingdom of Brega, located in Eastern Ireland, in the province of Leinster, where they held a family seat from very ancient times, long before the Norman Conquest of England in 1066 A.D.

Muircheartach Mac Lochlainn (died 1166), was king of Tír Eoghain, and High King of Ireland (c.1156-1166.) Together with sixteen of his closest allies, he was killed and was succeeded by Ruaidrí Ua Conchobair.

Niall Mac Lochlainn (died 1176) was a king of Cenél nEógain and Cenél Conaill, son of Muirchertach Mac Lochlainn.

United States McClaughlin migration to the United States +

Irish families left their homeland in astonishing numbers during the 19th century in search of a better life. Although individual reasons vary, most of these Irish families suffered from extreme poverty, lack of work opportunities, and exorbitant rents in their homeland. Many decided to travel to Australia or North America in the hopes of finding greater opportunities and land. The Irish immigrants that came to North America initially settled on the East Coast, often in major centers such as Boston or New York. But like the many other cultures to settle in North America, the Irish traveled to almost any region they felt held greater promise; as a result, many Irish with gold fever moved all the way out to the Pacific coast. Others before that time left for land along the St. Lawrence River and the Niagara Peninsula, or the Maritimes as United Empire Loyalists, for many Irish did choose to side with the English during the American War of Independence. The earliest wave of Irish migration, however, occurred during the Great Potato Famine of the 1840s. An examination of early immigration and passenger lists has revealed many people bearing the McClaughlin name:
