Migration of the O'fallon family

Thousands of Irish left in their homeland in the 18th and 19th centuries to escape the religious and political discrimination they experienced primarily at the hands of the English, and in the search of a plot of land to call their own. These immigrants arrived at the eastern shores of North America, early on settling and breaking the land, and, later, building the bridges, canals, and railroads essential to the emerging nations of United States and Canada. Many others would toil for low wages in the dangerous factories of the day. Although there had been a steady migration of Irish to North America over these years, the greatest influx of Irish immigrants came to North America during the Great Potato Famine of the late 1840s. Early North American immigration records have revealed a number of people bearing the Irish name O'fallon or a variant listed above: Stephen Fallon lived in Pennsylvania in 1773; and many other Fallons later joined him there in the mid 1800's. The family also settled in New York, California, Massachusetts, during the 19th century. They also settled in Newfoundland between 1850 and 1871..
