a bishop's see in the county of Cavan and province of Ulster in Ireland. It was called in former ages Clunus, or Clunis, i.e. the "sequestered place;" and is situated near Loch Ern. 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 1544, when Andrew Mac Brady bishop of Triburna erected a church on the site of that founded by St Fedlimid, to whose memory it was dedicated, and denominated Kilmore or "the great church." At present there are neither cathedral, chapter, nor canons, belonging to this see; the small parish church contiguous to the episcopal house serving for the purpose of a cathedral.
