Migration of the O'Mongant family to the New World and Oceana
began to immigrate to British North America and the United States in the 18th century, but the greatest influx of Irish immigrants came during the Great Potato Famine
of the late 1840s. The earlier settlers came to North America after a great deal of consideration and by paying relatively high fees for their passage. These settlers were primarily drawn by the promise of land. Those later settlers that came during the 1840's were trying to escape the conditions of poverty, starvation, disease, and death that had stricken Ireland
. Due to the enormity of their numbers and the late date of their arrival, these immigrants primarily became hired laborers instead of homesteading settlers like their predecessors. An exhaustive search of immigration and passenger lists has revealed many Irish immigrants North America bearing the name O'Mongant: John, Mary and Judy Mangan who arrived in New York State in 1853; Francis, Henry, James, John, Michael, Patrick, Thomas, and William Mangan, all arrived in Philadelphia, Pennsylvania between 1826 and 1868.
