Today's Irish surnames are underpinned by a multitude of rich histories. The name Dempser originally appeared in Gaelic as O Diomasaigh, from the word "diomasach," which means "proud."
Early Origins of the Dempser family
The surname Dempser 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 Dempser family to the New World and Oceana
A great mass of Ireland's native population left the island in the 19th century, seeking relief from various forms of social, religious, and economic discrimination. This Irish exodus was primarily to North America. If the migrants survived the long ocean journey, many unfortunately would find more discrimination in the colonies of British North America and the fledgling United States of America. These newly arrived Irish were, however, wanted as a cheap source of labor for the many large agricultural and industrial projects that were essential to the development of what would become two of the wealthiest nations in the western world. Early immigration and passenger lists indicate many people bearing the Dempser name: 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.
