The many Irish surnames in use today have long rich histories behind them. The name O'Mahombe originally appeared in Gaelic as Ó Mathghamhna, which is derived from the word mathghamhan, which means bear. 1 The modern Gaelic spelling is Ó Mahúna.

"Hugh Gharbh (or Hugh the Terrible), a younger brother of Laeghaire who is No. 93 on the 'O'Donaghue' (of Lough Lein) pedigree, was the ancestor of O'Mathamhna; anglicized O'Mahony and Mahony." 2

Early Origins of the O'Mahombe family

The surname O'Mahombe was first found in County Cork (Irish: Corcaigh) the ancient Kingdom of Deis Muin (Desmond), located on the southwest coast of Ireland in the province of Munster, where they held a family seat from ancient times.

"The O'Mahonys were anciently located in Cork and Kerry, where they were powerful Chiefs and sometimes styled Princes. They had several castles along the sea-coast. In County Cork an O'Mahony was Lord of Ivaugh, in the Barony of West Carbery, and an O'Mahony was Chief in Kinalea Barony. In County Kerry there was a Chief of the name in the Barony of Iveragh, and there were O'Mahonys in the Barony of Clanmaurice. The majority of persons of the name of Mahony or O'Mahony are still found in these two counties." 3

The Book of Munster clearly states: "The O'Mahony family were 'undisputed kings of Raithlean, and had a right to be kings of Cashel whenever that kingdom happened to be vacant; and from whom the Kings of Cashel had no right to demand anything except a bowing of the head.' " 2

Migration of the O'Mahombe family

Irish families began leaving their homeland for North America in the late 18th century. These families were usually modestly well off, but they were looking forward to owning and working on a sizable tract of land of their own. This pattern of emigration continued until the 1840s when the Great Potato Famine sparked a major exodus of destitute and desperate Irish people. These people were not leaving for a grant of land in North America because by this time the East Coast had reached its saturation point and free land was scarce. They were merely looking to escape the disease, starvation, and hopelessness that Ireland had fallen into. Although these unfortunate immigrants did not receive a warm welcome by the established populations in the United States and what would become Canada, they were absolutely critical to the rapid development that these two nations enjoyed. They would help populate the western lands and provide the cheap labor required for a rapid industrialization. An examination of passenger and immigration lists has revealed many early bearers of the name O'Mahombe or one of its variants: Cornelius, Daniel, Denis, James, Jeremiah, John, Mary, Michael, Patrick, Peggy, Thomas, Timothy and William Mahoney, who all arrived in Philadelphia, Pennsylvania between 1840 and 1860.
