Migration of the O'Sheehan family to the New World and Oceana
Often leaving from racial discrimination and colonial oppression, thousands of families left Ireland
in the 19th century for North America aboard passenger ships. Many early immigrants found a plot of land to call their own, something unimaginable for most Irish families
. Those that arrived later were often accommodated as laborers since there was a large demand for cheap labor. This was the fate for many of the families that arrived in North America during the Great Potato Famine
of the late 1840s. Whether they became agrarian settlers or industrial workers, the Irish that came to North America were invaluable for rapid development of the infant nations of the United States and Canada. Early North American immigration records have revealed a number of people bearing the Irish name O'Sheehan or a variant listed above: Cornelius Sheagan who arrived in Philadelphia, Pennsylvania in 1842; John, Morris and Thomas Sheehan arrived in Philadelphia between 1850 and 1870; Denis Sheeham arrived in Maryland in 1774.
