Migration of the McGuinnis family
Many Irish families did not fare so well within the English-ruled Ireland. Besides racial and religious discrimination, many families were renting out small tracts of farmland from absentee landowners at often unreasonable rates. Beginning in the late 18th century, moderately well off Irish families decided to emigrate to British North America or the United States in order to own their own plot of land. A radical change occurred in the 1840s, however, with the Great Potato Famine of the 1840s. Up to this point, the island's population had been increasing rapidly and a steady demand over the years for grain crops had depleted soil. Two failed crops and one poor one caused widespread disease and starvation. Thousands boarded ships looking for opportunities elsewhere. North America welcomed them as a source of cheap labor required for the many industrial and infrastructure projects underway, and as a means to quickly occupy the western regions. Research into immigration and passenger ship lists indicates that people bearing the name McGuinnis were among the earliest settlers to arrive in North America: John Guinnessy, who settled in New York in 1849; William Guinnes who settled in Barbados in 1663; Pat and Mary Guinnessy who settled in Quebec with their ten children in 1849..
