Irish names tend to vary widely in their spelling and overall form. The original Gaelic form of the name Cavanaugh is Caomhanach, an adjective denoting association with St. Caomhan. The first Kavanagh, Donal, the son of Dermot MacMurrough, was fostered by a successor of this saint.
The surname Cavanaugh was first found in County Carlow (Irish: Cheatharlach) a small landlocked area located in the province of Leinster in the South East of Ireland, where they held a family seat from very ancient times. The Kavanaghs (Cavanaghs) were descended from the MacMorough stem and were Lords of Leinster. Donoch McMorough was the King of Leinster, son of Dermod and it was from Donoch from which the Cavanaghs sprang. They were descended directly from the Heremon Line of Irish Kings. Donell, son of Dermot MacMurrough acquired the name Caomhanach, or Cavanagh. His sister Eva married Strongbow, Earl of Pembroke, the leader of the English invasion of Ireland. 
Many spelling variations of the surname Cavanaugh can be found in the archives. One reason for these variations is that ancient scribes and church officials recorded names as they were pronounced, often resulting in a single person being recorded under several different spellings. The different spellings that were found include Cavanagh, Kavanagh, Kavanah, Cavanaugh, Keevan, Cavanaw, Kavanaw, Cavenaugh, Cavanough, Cavaneagh, Cavana, Cavena, Cavinaugh, Kavina, Kavena, Kavanaugh, Cavanach, Kavanach, Cabenagh, O'Cavanagh, O'Kavanagh, Keaveney, Geaveney, M'Cavanna and many more.

In the 19th century, thousands of Irish left their English-occupied homeland for North America. Like most new world settlers, the Irish initially settled on the eastern shores of the continent but began to move westward with the promise of owning land. The height of this Irish migration came during the Great Potato Famine of the late 1840s. With apparently nothing to lose, Irish people left on ships bound for North America and Australia. Unfortunately a great many of these passengers lost their lives - the only thing many had left - to disease, starvation, and accidents during the long and dangerous journey. Those who did safely arrive in "the land of opportunities" were often used for the hard labor of building railroads, coal mines, bridges, and canals. The Irish were critical to the quick development of the infrastructure of the United States and Canada. Passenger and immigration lists indicate that members of the Cavanaugh family came to North America quite early:
