Before Irish names were translated into English, Callihan 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 Callihan is a patronymic name.
The surname Callihan was first found in Munster. The earliest mention of the name Callihan 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. 
One's name was often recorded under several different spellings during the life of its bearer during the Middle Ages. Spelling variations revealed in the search for the origin of the Callihan family name include 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.

In the 18th and 19th centuries hundreds of thousands of Irish people immigrated to North American shores. The early settlers were enticed by the promise of their own land, but they were moderately well off in Ireland when they decided to emigrate. Therefore, they were merely carrying out a long and carefully thought out decision. The 1840s saw the emergence of a very different trend: thousands of extremely desperate people crammed into passenger boats hoping to find any type of opportunity. The Irish of this decade had seen their homeland severely stricken by crop failures which resulted in widespread disease and starvation. At whatever time the Irish immigrants came to North America, they were instrumental in the rapid development of the emerging nations of the United States and what would become known as Canada. An exhaustive search of passenger and immigration lists has revealed many persons bearing the name Callihan, or one of its variants:
