Migration of the O'Derigan 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'Derigan: John Derick, who arrived in Philadelphia, Pennsylvania in 1865; Edward Derigan, who arrived in Philadelphia in 1875; the Widow Derrick, who settled in Georgia in 1738 with two sons and two daughters.
