Early Origins of the Shai family

The surname Shai was first found in County Kerry (Irish:Ciarraí) part of the former County Desmond (14th-17th centuries), located in Southwestern Ireland, in Munster province, where they held a family seat from ancient times.

The O'Shee variant claims Kilkenny as their ancestral home. At one time they were one of the most important of the ruling families of Kilkenny. Robert O'Shee was sovereign of the area in 1493. This family alternated using the "O'" prefix as not, as later his son Richard Shee, the Sovereign of Kilkenny (1545-1546) and (1553-1554) was Member of Parliament for Kilkenny in 1559.

Migration of the Shai family

In the 19th century, thousands of Irish left their English-occupied homeland for North America. Like most new world settlers, the Irish initially settled on the eastern shores of the continent but began to move westward with the promise of owning land. The height of this Irish migration came during the Great Potato Famine of the late 1840s. With apparently nothing to lose, Irish people left on ships bound for North America and Australia. Unfortunately a great many of these passengers lost their lives - the only thing many had left - to disease, starvation, and accidents during the long and dangerous journey. Those who did safely arrive in "the land of opportunities" were often used for the hard labor of building railroads, coal mines, bridges, and canals. The Irish were critical to the quick development of the infrastructure of the United States and Canada. Passenger and immigration lists indicate that members of the Shai family came to North America quite early: Daniel, James, John, Patrick, Thomas McShea all arrived in Philadelphia between 1840 and 1860; Bartholomew, David, Edward, Lawrence, James, John, Michael, Timothy O'Shea all arrived in Philadelphia between 1840 and 1860..
