Migration of the O'Lahertie family

The 18th century saw the slow yet steady emigration of Irish families to British North America and the United States. Those early Irish settlers that left their homeland were typically moderately well off: they were enticed by the promise of a sizable plot of land. However, by the 1840s, this pattern of immigration was gone: immigrants to North America were seeking refuge from the starvation and disease that the Great Potato Famine of that decade brought. The great numbers of Irish that arrived to the United States and the soon to be Canada were instrumental in their quick development as powerful industrial nations. An examination of early immigration and passenger lists uncovered many early immigrants bearing the name O'Lahertie: James Flaherty who landed in Virginia in 1651; followed James Flaharty in 1651; Timothy Flaharty settled in Boston Massachusetts in 1767; Ann Flaherty settled in New York in 1850.
