A massive wave of Irish immigrants hit North America during the 19th century. Although many early Irish immigrants made a carefully planned decision to leave left Ireland
for the promise of free land, by the 1840s immigrants were fleeing a famine stricken land in desperation. The condition of Ireland
during the Great Potato Famine
of the late 1840s can be attributed to a rapidly expanding population and English imperial policies. Those Irish families
that arrived in North America were essential to its rapid social, industrial, and economic development. Passenger and immigration lists have revealed a number of early Irish immigrants bearing the name O'Mannion: Mary Mannon, who settled in New England
in 1721; as well as Edward, James, John and Patrick Manion, who all arrived in Philadelphia between 1840 and 1860..
