The name Cochlyn 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 Cochlyn family

The surname Cochlyn 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.

Cochlyn Spelling Variations

Irish names recorded during the Middle Ages are characterized by many spelling variations. This preponderance of variations for common names can be explained by the fact that the scribes and church officials that kept records during that period individually decided how to capture one's name. These recorders primarily based their decisions on how the name was pronounced or what it meant. Research into the name Cochlyn revealed many variations, including Coghlan, Coughlan, MacCoughlan, McCoughlan, Coglan, Couglan, Coughlin and many more.

Migration of the Cochlyn family

Irish immigrants began to leave the English-controlled Ireland in sizable numbers during the late 18th century. Many of these Irish immigrated to British North America or the United States in the hopes of gaining their own tract of farmland. This pattern of migration grew steadily until the 1840s when the Great Potato Famine caused a great exodus of immigrants to North America. These immigrants differed from their predecessors in that they were desperately fleeing the disease and starvation that plagued their homeland, and many were entirely destitute when they arrived in North America. Although these penniless immigrants were not warmly welcomed when they arrived, they were critical to the rapid development of the United States and what would become known as Canada. Many went to populate the western frontiers and others provided the cheap labor the new manufacturing sector and the building of bridges, roads, railways, and canals required. A thorough examination of immigration and passenger lists has revealed some of the earliest people to arrive in North America with name Cochlyn or one of its variants: 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 Cochlyn 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.
