Thus they became the "Ciannachta" – 'the people of St Cianan.' fortuitously, the ancestor figure of their neighbours Gailenga and Luigni – Cian mac Ailella Auluimm – would have provided a suitably named ancestor figure when they later sought to construct a new pedigree for themselves." Cianan was regarded as a very significant figure in very early Irish Christianity, his church at Duleek traditionally stated as the first stone church in Ireland. Cianan himself is reported in the Annals of Ulster as dying in 489, four years before Saint Patrick. No life is extant, but various anecdotes survive, particularly in the medieval commentary on the martyrology Félire Óengusso. The territorial extent of Ciannachta Breg prior to its conquest is uncertain, but believed to have been reasonably large.
