Today's Irish surnames are underpinned by a multitude of rich histories. The name MacDempsy originally appeared in Gaelic as O Diomasaigh, from the word "diomasach," which means "proud."
Early Origins of the MacDempsy family
The surname MacDempsy 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 MacDempsy family to the New World and Oceana
The 19th century saw a great wave of Irish families
for the distant shores of North America and Australia
. These families often left their homeland hungry, penniless, and destitute do to the policies of England
. Those Irish immigrants that survived the long sea passage initially settled on the eastern seaboard of the continent. Some, however, moved north to a then infant Canada as United Empire Loyalists after ironically serving with the English in the American War of Independence
. Others that remained in America later joined the westward migration in search of land. The greatest influx of Irish immigrants, though, came to North America during the Great Potato Famine
of the late 1840s. Thousands left Ireland
at this time for North America, and those who arrived were immediately put to work building railroads, coal mines, bridges, and canals. In fact, the foundations of today's powerful nations of the United Sates and Canada were to a larger degree built by the Irish. Archival documents indicate that members of the MacDempsy family relocated to North American shores 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.
