The Irish name O'Kelley has a long Gaelic heritage to its credit. The original Gaelic form of the name O'Kelley is Ó Ceallaigh or Mac Ceallaigh. These names denote descendants of Ceallach. This personal name may be derived from the word "ceallach," which means "strife." 1

Early Origins of the O'Kelley family

The surname O'Kelley was first found in southwest Ireland, south of Dublin where they held a family seat from very ancient times. The Kelly surname is conjecturally descended from King Colla da Crioch, who died in 357 A.D.

While most of the family claim Ireland as their heritage, we did find one reference in England: "Kelly, [Devon] is noteworthy as affording one of the few continuing local instances of families seated on the estates whence they take name. The Kellys of Kelly have held this manor from the time of Henry II. at least. " 2

Henry II, King of England reigned from 1154 to 1189; so one may presume there is a relationship between the Irish and the English families, but this is the extent of our research at this time.

United States O'Kelley migration to the United States +

During the 19th century thousands of impoverished Irish families made the long journey to British North America and the United States. These people were leaving a land that had become beset with poverty, lack of opportunity, and hunger. In North America, they hoped to find land, work, and political and religious freedoms. Although the majority of the immigrants that survived the long sea passage did make these discoveries, it was not without much perseverance and hard work: by the mid-19th century land suitable for agriculture was short supply, especially in British North America, in the east; the work available was generally low paying and physically taxing construction or factory work; and the English stereotypes concerning the Irish, although less frequent and vehement, were, nevertheless, present in the land of freedom, liberty, and equality for all men. The largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. Research into passenger and immigration lists has brought forth evidence of the early members of the O'Kelley family in North America:
