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.
A study of the Bréifne school of poetry is forthcoming from Pádraigín Ní Uallacháin.
Mac Maoláin was a surname borne by a number of unrelated families in Gaelic Ireland, found in Breifne, Mide, Brega, Connacht and Ulster.
