 T.M.Charles-Edwards suggests that the site may have belonged originally to the province of Leinster rather than Mide, but that the political geography had changed by the 8th century, when much of southern Brega was divided between different septs of the Síl nÁedo Sláine.By that time, Domnach Sechnaill lay in the kingdom of the Uí Chernaig, close to the royal crannóg seat in Loch nGabor, as did the churches of Trevet and Kilbrew.
