Migration of the O'Mangyn family to the New World and Oceana
The English-ruled Ireland
of the late 18th and 19th centuries featured a rapidly increasing population and an agricultural-based economy. This combination proved to be disastrous in the 1840s after a couple of failed potato harvests. Thousands died of disease and starvation, and thousands more left the country, often bound for North America. Those that survived the journey to North America were put to work building the bridges, canals, roadways, and railways needed for the development of an industrial society. Those Irish, although often despised by those already established in North American cities and towns, played an instrumental role in making Canada and the United States the powerful and wealthy nations that they are today. An examination of early immigration and passenger lists has shown many immigrants bearing the name O'Mangyn: 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.
