Carrickabraghy Castle is located on an outcropping of rock at the southern entrance of Trawbreaga Bay in the Inishowen Peninsula, County Donegal. The castle protected a small peninsula in north-western Inishowen known as the Isle of Doagh. (It was an island once in prehistory).
In pre-Viking years, Carrickabraghy (as well as the Isle of Doagh) was ruled by the Cenel Coelbad, descendants of Eoghan (who was son of the Irish High King, Niall of the Nine Hostages). Coelbad was the grandson of Eoghan. Many Irish septs are descended from the kings of Carrickabraghy, including my own (O’Gaillin). From forts located at the site of the present castle, the kings of Carrickabraghy defended Inishowen from attacks.
From the 9th century onward,the land was ruled by the O Maolfabhail (McFall) sept who protected Inishowen from Viking raids and raids by other foreigners.
Sometime after 1200 AD, the rulers of Inishowen came from the O Dochartaigh (O’Doherty) clan. Carrickabraghy Castle was probably built around 1590 by Phelim Brasleach O’Doherty. It was one of a chain of several O’Doherty castles that protected the peninsula. The castle was originally built with a keep and two towers surrounded by a bawn wall. Today the castle ruins has only the keep and part of one tower.
One of the castle’s famous residents was young Sir Cahir O’Dohery, Lord of Inishowen. Cahir took the English side in the Nine Years War with the Irish Earls. At the conclusion of the war, he was suspected of planning to retake Ireland with help from Spain. He began a poorly conceived rebellion in 1608 when he captured and burned Derry City, Strabane, and other English controlled sites before being defeated and killed near the Rock of Doon in Kilmacrenan, Donegal.

Good morning, my name is Lisette Galain. I live in Uruguay (South America). As I know my ancestors were Basques. But I also know that before that they came from Ireland escaping the famine. As far as I know, my surname in its Gaelic form was O ‘Gaillinn. Today I am 35 years old and since I remember I have always felt a strong connection with Ireland, which I can not explain. The little that I have been able to investigate leads me to that the root of my last name would be in the zone of Donegal mainly. Could you please confirm if this is true? I look forward to your reply. Thank you very much for your time.
Best regard, Lisette Galain._
Hello Lisette: If your ancestors emigrated from Ireland during the famine, there is a good chance that they came from Donegal or across the border in Tyrone. At that time, the Anglicised version of their name was probably Gallan, Gallon, or Gallen. As I mention in my Carrickabraghy post, the O’Gaillins (various spellings of Gallen) descended from the king of Carrickabraghy and Carrickabraghy is in Donegal. It seems very likely that your ancestors came from that part of Ireland, particularly from the Finn and Derg Valleys.
You could always consider some level of Y DNA testing of a male Galain. Y chromosomes of this region of Ireland are fairly well tested so there should/would be many matches to give you a better picture of your surname roots.
My family are from this area, and were originally McFall.
