Migration of the O'Hennessy family to the New World and Oceana


Thousands of Irish families left for North American shores in the 19th century. These people were searching for a life unencumbered with poverty, hunger, and racial discrimination. Many arrived to eventually find such conditions, but many others simply did not arrive: victims of the diseased, overcrowded ships in which they traveled to the New World. Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States. A thorough examination of passenger and immigration lists has disclosed evidence of many early immigrants of the name O'Hennessy: William Hennesey who settled in Philadelphia, Pennsylvania in 1874; Edmund, Edward, James, Michael, Patrick and Robert Hennessey settled in Philadelphia between 1850 and 1870.
