Last name: Devlin

This interesting surname is of Irish origin, and is an anglicization of the Old Gaelic "O'Dobhailein". The Gaelic prefix "O" indicates "grandson" or "male descendant of", plus the personal byname "Dobhailein", from "dobhail" meaning "unlucky" or "unfortunate". Traditionally, Irish family names are taken from the heads of tribes, or from some illustrious warrior, and are usually prefixed by "O" (as above), or "M(a)c", denoting "son of". The principal (O) Devlin sept belonged to County Tyrone; their territory lay on the Tyrone shore of Lough Neagh and was known as Munterdevlin, the first element coming from the Gaelic "muntir", country or territory. Today the name is chiefly found in Tyrone and its adjacent counties. The second main sept belonged to County Sligo, and their territory lay in the barony of Corran. In 1316, one Gillananaev O'Devlin, of the county, standard bearer to the O' Connors, was slain in battle. The name is still prominent in Counties Sligo, Leitrim and Cavan, but has, in some areas, been widely changed to Dolan. Anne Devlin (1778 - 1851) was the faithful servant of the Irish patriot Robert Emmet, who though imprisoned and tortured refused to give information against him. The first recorded spelling of the family name is shown to be that of O' Devlin, which was dated died 1211, Bishop of Kells, during the reign of Cathal "Crabhhearg" (Red Hand), King of Ireland, 1198 - 1224. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.

I now know more about my whole 'cause my first name either means 'Barn' in Irish or 'Asked for' in Hebrew and my second name is 'Unlucky' That's just great. Thanks for giving me the information it was great! =)

The name means Raging Valor

For those who are interested in the truth,The History of the Sept Devlin was first published in 1688,as recorded by Burkes peerage. A mose recent publication The History of an Irish Sept:Devlin ,published by R Develin D.Oxford,professor Haverford College,Pa in 1936 shows the extensive 78 page footnoted history of the Sept.This can be found in the Library of Congress..Neither the history presented on this web-sight nor the coat of arms are correct.Additionally,a distinct Sept also exists in the lowlands of Scotland,with its own coat of arms etc.The corporation is simply a shrill for crown forces and their ilk.

Can you help me concerning the Devlins of Scotland? My tree goes back to the Devlins of Ireland, but the had left Scotland, do I believe my history may be the ones you mentioned here. Any help would be greatly appreciated


I come from the shores of Lough Neagh and there sure are a lot of Devlins living there. So what part of this database is accurate and what is not? Or are you working for a rival database?

The Irish surname O'Develin fo which Devlin is derived from has its origin in the Irish sept name O'Dobhuilen which means "Raging Valor" I highly doubt the academic quality of research from and its affiliates.
