Cos. Cavan & Leitrim plus bits of adjoining cos. constituted the area of the Kingdom of Breifne, which was in the early 12th century coextensive with the Catholic Diocese of Kilmore. A number of surnames have been associated with the Breifne area since the 11th, 12th and 13th centuries, and according to the traditional genealogies are descended from a common male-line ancestor who lived in the 6th century. Some branches of these families later split off and took on other surnames, and families bearing surnames originating elsewhere (some perhaps identical or very similar to a Breifne surname) moved in over the succeeding centuries. This project is concerned with all of these surnames.
