a bishop's see in the county of Cavan and province of Ulster in Ireland. It was called in former ages Clunes, or Clunis, i.e. the "sequestered place;" and is situated near Lough Earn. St Fedlimid founded this bishopric in the sixth century; it was afterwards removed to an obscure village called Triburna; where it continued until the year 1454, when Andrew Machbrady bishop of Triburna erected a church on the site of that founded by Fedlimid, to whose memory it was dedicated, and denominated Kilmore, or "the great church." At present there is neither cathedral, chapter, nor canons, belonging to this see; the small parish church contiguous to the episcopal house serving the purpose of a cathedral.
