The name Dempsey originally appeared in Gaelic as O Diomasaigh, from the word "diomasach," which means "proud."
Names from the Middle Ages demonstrate many spelling variations. This is because the recording scribe or church official often decided as to how a person's name was spelt and in what language. Research into the name Dempsey revealed many variations, including Dempsey, O'Dempsey, Dempsy, Dempsay, Dempsie and many more.
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.

The 19th century saw a great wave of Irish families leaving Ireland 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 Dempsey family relocated to North American shores quite early:
