Migration of the Illroy family to the New World and Oceana
began to migrate to North America in the late 18th century in the hopes of gaining their own plot of land. The majority of these early immigrant families were relatively well off because the transatlantic passage was costly. As a result the decision to immigrate was carefully made. Those immigrants that arrived in the late 1840s differed because their decision to leave was in direct response to the Great Potato Famine
. Many of the families that crossed the Atlantic during this decade were destitute, either having spent all they had on the fare or even starting with nothing, but being sponsored by a philanthropic society. Whenever, these Irish families
came to North America, they were made great contributions to the developing nations of the United States and what would come to be known as Canada: the earlier settlers as land clearing homesteaders, and the later immigrants as the muscle that would build the industries and routes of transportation so critical to a powerful nation. Research into the passenger and immigration lists has shown many early and significant Irish immigrants bearing the name Illroy: John MacElroy, who landed in Pennsylvania in 1798; and James Gilroy, who settled in Pennsylvania in 1864; they also settled in Massachusetts, New York, and California between 1765 and 1854. The Kilroys also settled in the above states between the same periods.
