The Uí Bairrche kindred of the Laigin took their name from Dairé Barrach, a son of Cathair Mór, who lived during the 2nd century AD. It is possible that they are mentioned in Ptolemy's Geographia as the Brigantes; it is unknown what connection, if any, they have to similarly named groups in Britain or Europe. Ptolemy may have simply used the term because of its phonetic similarity. In any case, Dairé lived at Dún Ailinne, one of the ancient Gaelic royal sites of Ireland and capital of the Laigin, located in what is now County Kildare. From here he gained a pupil in Mug Nuadat, ancestor of the Eóganachta, whom he supported in becoming King of Munster in conflict with Conn of the Hundred Battles. Dáire himself may have been High King of Ireland for a difficult month if the 7th century AD poem about the early Kings of Tara named Baile Chuinn Chétchathaig is to be believed.
