Irish emigration to North America began modestly in the late 18th century. At this time, Irish families made the journey to British North America and the United States by choice and after careful consideration: they were primarily in search of a suitably large stretch of land to call their own. This pattern would change most dramatically during the Great Potato Famine of the late 1840s.
