Origin of the Name Devlin
family history was found in the allfamilycrests.com archives. The Irish name Devlin is derived from the Gaelic O'Doibhilin sept who were located in what is now the barony of Corran, County Sligo.
A sept or clan is a collective term describing a group of persons whose immediate ancestors bore a common surname and inhabited the same territory. Irish septs and clans that are related often belong to even larger groups, sometimes called tribes.
The principal sept of the name however, was located in County Tyrone. Their chiefs were lords of the territory known as Munterdevlin on the Tyrone shore of Lough Neagh. The majority of present day Devlins are from Ulster , most of whom hail from Tyrone. The prefix O is seldom if ever used in modern times. The best known of the name were associated with Counties Wicklow and Tyrone. Anne Devlin, 1778-1851, was the faithful servant of Robert Emmet who, though imprisoned and tortured, would not give information against him.
The Devlin coat of arms came into existence centuries ago. The process of creating coats of arms (also often called family crests) began in the eleventh century although a form of Proto-Heraldry may have existed in some countries prior to this. The new art of Heraldry made it possible for families and even individual family members to have their very own coat of arms, including all Devlin descendants.
