Migration of the Ilrea family to the New World and Oceana
, as an English-controlled colony in the 19th century, suffered the loss of hundreds of thousands of its native people. The system of land ownership often did not sufficiently provide for the tenants who farmed the land. This was most clearly evidenced in the Great Potato Famine
of the 1840s. Previous years of great demand for grain products and livestock had run the land down. Many landowners foreseeing an upcoming crisis often removed families from the land or forced them to rely on pitifully small plots where only a subsistence living could be made. When the famines of 1845, 46, and 48 hit, many had nothing. Disease and starvation became widespread and families boarded ships for elsewhere any way they could. Those who went to America were instrumental in developing the industrial power known today: many Irish were employed in hard labor positions in factories and in building the bridges, canals, roads, and railways necessary for a strong industrial nation. Research of early immigration and passenger lists has shown that many bearers of the name Ilrea: 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.
