Migration of the Kylly family

Suffering from poverty and racial discrimination, thousands of Irish families left the island in the 19th century for North America aboard cramped passenger ships. The early migrants became settlers of small tracts of land, and those that came later were often employed in the new cities or transitional work camps. The largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. Although the immigrants from this period were often maligned when they arrived in the United States, they provided the cheap labor that was necessary for the development of that country as an industrial power. Early immigration and passenger lists have revealed many immigrants bearing the name Kylly: 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.
