a bishop's see in the county of Cavan and province of Ulster in Ireland. It was called in former ages Clunes, or Clanis, i.e. the "sequestrated place;" and is situated near Lough Eamh. 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 Macbrady 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.
