Migration of the O'Keily family

Irish families fled the English-colonized Ireland in record numbers during the 19th century for North America. Many of those destitute families died from disease during, and even shortly after, the long journey. Although those that immigrated before the Great Potato Famine of the 1840s often were granted a tract of land, those that arrived later were generally accommodated in urban centers or in work camps. Those in the urban centers would labor in the manufacturing sector, whereas those in work camps would to build critical infrastructures such as bridges, canals, roads, and railways. Regardless of when these Irish immigrants came to North America, they were critical for the rapid development of the young nations of the United States and Canada. Early immigration and passenger lists have recorded many early immigrants bearing the name of O'Keily: 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.
