The name O'Cocklant has undergone many variations in the time that has passed since its genesis. In Gaelic it appeared as Mac Cochlain or Ó Cochlain. 1

Early Origins of the O'Cocklant family

The surname O'Cocklant was first found in Munster where Dealbha, brother of King Blad of Munster, is the traditional ancestor of this family. There were two different septs which have become known as Coughlan: the MacCoughlans, who dwelled in the barony of Garrycastle in Offaly, and the O'Coughlans, who lived in the baronies of Carbery and Ballymore in Cork. In Cork, they occupied the territories known as the baronies of Carbery and Ballymore.

The MacCoughlans were the more important of the two septs until they dissolved and scattered during the 18th century. They were a Dalcassian sept, and their chief was referred to as Chief of Delvin MacCoughlan. In 1858, they were still recorded as landlords at Cloghan, near Banagher, but they vanished within fifty years. However, the O'Coughlans, who were recorded in large numbers at the time of the 1659 census, still continue to be numerous in those territories. This census shows the prefix O to have been largely discarded by that time. The MacCoghlans lost most of their extensive territories during the Anglo Norman invasion of Ireland by Strongbow in 1172, and lost even more during the Cromwellian Invasion in 1641.

Migration of the O'Cocklant family

Irish families fled the English-colonized Ireland in record numbers during the 19th century for North America. Many of those destitute families died from disease during, and even shortly after, the long journey. Although those that immigrated before the Great Potato Famine of the 1840s often were granted a tract of land, those that arrived later were generally accommodated in urban centers or in work camps. Those in the urban centers would labor in the manufacturing sector, whereas those in work camps would to build critical infrastructures such as bridges, canals, roads, and railways. Regardless of when these Irish immigrants came to North America, they were critical for the rapid development of the young nations of the United States and Canada. Early immigration and passenger lists have recorded many early immigrants bearing the name of O'Cocklant: Francis Coghlan settled in Philadelphia, Pennsylvania in 1879; James Coghlan settled in New York in 1812; James Coghlin settled in Boston Massachusetts in 1766.



The O'Cocklant Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Fortis in arduis
Motto Translation: Brave in difficulties.
