Today's Irish surnames are underpinned by a multitude of rich histories. The name O'Dempsey originally appeared in Gaelic as O Diomasaigh, from the word "diomasach," which means "proud."
Early Origins of the O'Dempsey family
The surname O'Dempsey 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]

O'Dempsey Spelling Variations

during the Middle Ages was an inconsistent endeavor at best. Since the general population did not know how to read or write, they could only specify how their names should be recorded orally. Research into the name O'Dempsey revealed spelling variations
, including Dempsey, O'Dempsey, Dempsy, Dempsay, Dempsie and many more.

Migration of the O'Dempsey family to the New World and Oceana
left their homeland in astonishing numbers during the 19th century in search of a better life. Although individual reasons vary, most of these Irish families
suffered from extreme poverty, lack of work opportunities, and exorbitant rents in their homeland. Many decided to travel to Australia
or North America in the hopes of finding greater opportunities and land. The Irish immigrants that came to North America initially settled on the East Coast, often in major centers such as Boston or New York. But like the many other cultures to settle in North America, the Irish traveled to almost any region they felt held greater promise; as a result, many Irish with gold fever moved all the way out to the Pacific coast. Others before that time left for land along the St. Lawrence River and the Niagara Peninsula, or the Maritimes as United Empire Loyalists, for many Irish did choose to side with the English during the American War of Independence
. The earliest wave of Irish migration, however, occurred during the Great Potato Famine
of the 1840s. An examination of early immigration and passenger lists has revealed many people bearing the O'Dempsey 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.
