Migration of the O'Quelly family
The 18th and 19th centuries saw many Irish families immigrate to North America in search of land and opportunities. The largest influx of Irish immigrants to the United States and British North America came during the 1840s when the Great Potato Famine laid waste to their homeland. Hundreds of thousands left the island in an attempt to escape the starvation and disease it brought. Although the arrival of such a large number of destitute Irish was not welcomed by the established population in the United States and what would become known as Canada at the time, these Irish were an essential element to the rapid development of these growing industrial nations. They filled the demand for the cheap labor needed for the work in factories and in the construction of bridges, roads, canals, and railways. An examination of passenger and immigration lists has revealed many immigrants bearing the name of O'Quelly or one of its variants: William Keeley who landed in America in 1765; Dennis and Ellen Keeley settled in Boston Massachusetts in 1849; Michael Keeley settled in Philadelphia, Pennsylvania in 1852.
