Migration of the Jilen family

In the late 18th century, Irish families began emigrating to North America in the search of a plot of land to call their own. This pattern of emigration grew steadily until the 1840s when the Great Potato Famine of the 1840s cause thousands of Irish to flee the death and disease that accompanied the disaster. Those that made it alive to the shores of the United States and British North America (later to become Canada) were, however, instrumental in the development of those two powerful nations. Many of these Irish immigrants proudly bore the name of Jilen: Hugh and Jane Gillan who settled in New York State in 1823; James Gillan settled in New York in 1803; John, Patrick, Thomas and William Gillan settled in Philadelphia between 1840 and 1860.
