Migration of the O'Mongun family to the New World and Oceana
The 18th century saw the slow yet steady emigration of Irish families
to British North America and the United States. Those early Irish settlers that left their homeland were typically moderately well off: they were enticed by the promise of a sizable plot of land. However, by the 1840s, this pattern of immigration was gone: immigrants to North America were seeking refuge from the starvation and disease that the Great Potato Famine
of that decade brought. The great numbers of Irish that arrived to the United States and the soon to be Canada were instrumental in their quick development as powerful industrial nations. An examination of early immigration and passenger lists uncovered many early immigrants bearing the name O'Mongun: 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.
