Where did the Irish Cellaghan family come from? What is the Irish Cellaghan family crest and coat of arms? When did the Cellaghan family first arrive in the United States? Where did the various branches of the family go? What is the Cellaghan family history?Before Irish names were translated into English, Cellaghan had a Gaelic form of O Ceallachain, possibly from "ceallach", which means "strife". The family is descended from Ceallachan (Callaghan), the 10th century King of Munster from whom their surname is derived, and as such, the name Cellaghan is a patronymic name.
The general population of Ireland, like those of Europe and Britain during the Middle Ages, scribes recorded people's names as they saw fit. As a result, surnames often had many spelling variations. For Cellaghan some of these variations included: Callaghan, Callahan, O'Callaghan, O'Callahan, Calahan, Cellaghan, Kalahan, Kallaghan, Kallahan, O'Kallaghan, Kellaghan, Kelleghan, Kellahan, Kelahan, Ceilahan, Ceilaghan, Callachan, Calachan, Callagan, Calagan, Kelagan, Callighan and many more.
First found in Munster. The earliest mention of the name Cellaghan placed them in the barony of Kinlea, in County Cork, yet the family lost most of their original lands in the barony of Kinelea during the Anglo- Norman Conquest under Strongbow. They relocated to an area near Mallow, in the north of the county, and remained there until forced off their lands once again during the Cromwellian Invasion of the 17th century. The head family migrated to the east of County Clare and flourished, giving their name to the village of Callaghan's Mills. The resumption of the often-discarded prefix "O" has been widespread during the late twentieth century, but in the early twentieth century, Callaghans greatly outnumbered O'Callaghans, but such is no longer the case. The O'Callaghans are one of the few Irish families to still have a chief, certified by the Genealogical Office.

The 18th and 19th centuries saw many Irish families immigrate to North America in search of land and opportunities. The largest influx of Irish immigrants to the United States and British North America came during the 1840s when the Great Potato Famine laid waste to their homeland. Hundreds of thousands left the island in an attempt to escape the starvation and disease it brought. Although the arrival of such a large number of destitute Irish was not welcomed by the established population in the United States and what would become known as Canada at the time, these Irish were an essential element to the rapid development of these growing industrial nations. They filled the demand for the cheap labor needed for the work in factories and in the construction of bridges, roads, canals, and railways. An examination of passenger and immigration lists has revealed many immigrants bearing the name of Cellaghan or one of its variants: James Callaghan who settled in America in 1768; Gerhard Callaghan settled in 1764; James Callaghan settled in Pennsylvania in 1772; John Callaghan settled in Boston Massachusetts in 1764.
