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, industial, and economic development. Passenger and immigration lists have revealed a number of early Irish immigrants bearing the name Shanahan: Charles Shannon, who arrived in America in 1742; James Shanahan, who was a laborer in St. John's, Newfoundland, in 1779; Bridget Shannon, who was on record in Massachusetts in 1813.
