Irish names tend to vary widely in their spelling and overall form. The original Gaelic form of the name O'Kavanna 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.

Early Origins of the O'Kavanna family

The surname O'Kavanna 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. 1

Migration of the O'Kavanna family

A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination. This Irish exodus was primarily to North America. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world. Early immigration and passenger lists indicate many people bearing the O'Kavanna name: Charles, Dudley, James, John, Joseph, Michael, Nicholas, Peter, Robert, Thomas and William Cavanagh, who all arrived in Philadelphia, Pennsylvania between 1813 and 1880.
