[2] The Dál Riata, presumably settling in far northeastern Ulster in the prehistoric period, would famously go on to contribute to the founding of the Kingdom of Alba or Scotland and be responsible for the Gaelicisation of that country.
The most celebrated Royal Family of Scotland, the House of Dunkeld, described themselves as the "seed of Conaire Mór" as late as the twelfth century.
According to tradition, the last king in the 'direct' male line from the Clanna Dedad and Síl Conairi was Alexander III of Scotland (d. 19 March 1286).
Although an earlier, prehistoric Gaelic presence in Scotland has long been noted by scholars, two early Kings of the Picts suggested to be from the Dál Riata, and who may have been instrumental in the (further) Gaelicisation of Pictland, were Bridei IV of the Picts and his brother Nechtan mac Der-Ilei.
The birth, life, and fall of Conaire Mór are recounted in the epic tale Togail Bruidne Dá Derga.
