Today's Irish surnames are underpinned by a multitude of rich histories. The name MacDempsey originally appeared in Gaelic as O Diomasaigh, from the word "diomasach," which means "proud."
Early Origins of the MacDempsey family
The surname MacDempsey was first found in King's County and Queen's County, where they were traditional Chiefs of Calnmaliere, a territory that lay on both sides of the river Barrow. It contained parts of Geashill and Phillipstown in Kings County and parts of Portnehinch in Queen's County. They claim descent through the O'Connors of Offaly
, specifically the 2nd century Irish King, Cathair Mor. CITATION[CLOSE]

Migration of the MacDempsey family to the New World and Oceana
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 MacDempsey family came to North America quite early: Ann, Biddy, Bridget, Catherine, John, and Henry Dempsey who settled in Quebec in 1840; Edward Dempsey settled in New York in 1810; Jeremiah Dempsey settled in Mississippi in 1820.
