Life
On 17 May (Old Style) the Martyrology of Donegal records Holy Hierarch Siollan, as a bishop; the year of repose given is 658. A later hand adds the place, Daimhinis, and the year. The same name also appears in the Martyrology of Tallaght and Gorman's martyrology. No other secure details survive, and veneration remains local, without synodal canonization.
