According to Samuel Lewis, in 1837 the Church of Ireland living was a rectory in the diocese of Cashel, formed at a time earlier than extant records by uniting the vicarages of Boly or Galvoly (civil parish of Galbooly) and Drom with the chapelry of Leogh (Leigh). There are two villages in the parish: Two-Mile Borris and Littleton.

The English-language name Borrisleigh is derived from the Irish-language Buiríos Léith, as is the last word in the alternative English-language name for the parish, Two-Mile Burris.
