Bishop of Kilmore

The Bishop of Kilmore is an episcopal title which takes its name after the parish of Kilmore, County Cavan in Ireland. In the Roman Catholic Church it remains a separate title, but in the Church of Ireland it has been united with other bishoprics.

The see of Kilmore was originally known as Breifne (Latin: Tirbrunensis, Tybruinensis or Triburnia; Irish: Tír mBriúin, meaning "the land of the descendants of Brian", one of the kings of Connaught) and took its name after the Kingdom of Breifne.

The see became one of the dioceses approved by Cardinal Giovanni Paparoni at the synod of Kells in 1152, and has approximately the same boundaries as those of the ancient Kingdom of Breifne. In the Irish annals, the bishops were recorded of Breifne, Breifni, Breifny, Tir-Briuin, or Ui-Briuin-Breifne.

In the second half of the 12th century, it is likely the sees of Breifne and Kells were ruled together under one bishop. In 1172, Tuathal Ua Connachtaig took the oath of fealty to King Henry II of England as bishop of Kells. Soon after 1211 the see of Kells was incorporated into the diocese of Meath.

In 1454, Pope Nicholas V gave permission for the then bishop, Aindrias Mac Brádaigh (Anglicised: Andrew McBrady), to have the ancient church at Kilmore, founded in the 6th century by Saint Felim (or Feithlimidh), to be the cathedral church of the diocese. This building passed into the hands of the Church of Ireland at the Reformation, and, following the construction of a new cathedral, is now used as a parochial hall.
