The name O'Coglen has undergone many variations in the time that has passed since its genesis. In Gaelic it appeared as Mac Cochlain or O Cochlain.
Early Origins of the O'Coglen family
The surname O'Coglen 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
in 1172, and lost even more during the Cromwellian Invasion

O'Coglen Spelling Variations
One explanation for the many variations is that scribes and church officials frequently spelled the name as it sounded: an imprecise method at best. Understandably then, various spellings of the surname O'Coglen were found in the many archives researched. These included Coghlan, Coughlan, MacCoughlan, McCoughlan, Coglan, Couglan, Coughlin and many more.

Migration of the O'Coglen family to the New World and Oceana
A great wave of Irish migration occurred during the 19th century as a direct result of English colonial rule and tight-fisted absentee landlords. Many of these Irish immigrants boarded passenger ships bound for North America. Those who migrated early enough were given land in either British North America or the United States; those who came in the late 19th century were typically employed in industrial centers as laborers. At whatever age they undertook the dangerous passage to North America, those Irish immigrants were essential to the speedy development of the two infant nations to which they arrived, whether they broke and settled land, helped build canals, bridges, and railroads, or produced products for consumer consumption. An examination of immigration and passenger lists has uncovered a large number of immigrants bearing the name O'Coglen 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 O'Coglen 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.
