Etymology of O'Collant

What does the name O'Collant mean?

While many Irish names are familiar, their past incarnations are often shrouded in mystery, reflecting the ancient Gaelic heritage of their bearers. The original Gaelic form of the name O'Collant is "Mac Cuilinn" or "Ó Cuilinn," which are from the word "cuileann," which means "holly." 1

They descend from Heber, who with his brother Heremon ruled Ireland. 2 Culen or Colin, son of Indulph, was King of Scotland or Alba (967-71?) "His father, Indulph, was the first king who occupied Edinburgh, up to that time within Anglian Northumbria. " 3

Early Origins of the O'Collant family

The surname O'Collant was first found in the southeast of Ireland, in the counties of Dublin, Wicklow, and Wexford. Although all but one of the many distinct septs have become extinct, this remaining sept currently provides Ireland with nearly 8000 members, enough to make Cullen the 84th most common name in Ireland.

Descended from Olioll Flann Beag, king of Munster, the Cullens made their original homeland at Glencullen, in Wicklow, and they have remained there to the present day, despite the threat of their more powerful neighbors, the O'Tooles and the O'Byrnes. They were an influential family, as indicated by the inclusion of Cullen of Cullenstown among the leading gentry of Wexford in the Clongowes manuscript of 1598.

Due to the prominence of this sept, a number of similarly-named minor septs also adopted the name Cullen, including O Cuileamhain of south Leinster, which is also rendered Culloon or Culhoun, and Mac Cuilin of Leitrim, which is also Anglicized MacCullen.

Migration of the O'Collant family

Suffering from poverty and racial discrimination, thousands of Irish families left the island in the 19th century for North America aboard cramped passenger ships. The early migrants became settlers of small tracts of land, and those that came later were often employed in the new cities or transitional work camps. The largest influx of Irish settlers occurred with Great Potato Famine during the late 1840s. Although the immigrants from this period were often maligned when they arrived in the United States, they provided the cheap labor that was necessary for the development of that country as an industrial power. Early immigration and passenger lists have revealed many immigrants bearing the name O'Collant: Henry Cullen who settled in Boston Massachusetts in 1820; L. Cullen settled in Baltimore in 1820; Patrick Cullen settled in West New Jersey in 1772; the family also settled in New York and California in the 19th century. Popular Christian names of the settlers was Andrew, Bernerd, Charles, Daniel, Dennis, Edward, George, James, John, Michael, Owen, Patrick, Peter, Robert, Thomas, Walter, and William, and they settled mostly in Philadelphia between 1830 and 1870. William Cullen was a property owner in St. John's Newfoundland in 1794 and had been settled there for 17 years.
