Sheahan migration to the United States +

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. For example, the years 1825-1845 saw approximately 450,000 heading to British North America and 400,000 to the United States, but in 1847, at the height of the famine, it is estimated that more than 104,000 Irish immigrants went to British North America and more than 119,000 to the United States. An examination of passenger and immigration lists has revealed many early immigrants bearing the name Sheahan:
