Kilkelly was a native of County Galway. His family, Mac Giolla Cheallaigh, were a branch of the dynasty that once ruled Ui Fiachrach Aidhne, a kingdom occupying roughly the same land area as the diocese of Kilmacduagh.

A member of the Dominican Order, Kilkelly was appointed 22 June and consecrated 14 October 1744, and became Apostolic Administrator of Kilfenora when the two dioceses united in September 1750.

Bishop Kilkelly died on 29 May 1783. On his death, Kilfenora was united to the diocese of Kilmacduagh under Laurence Nihell (or Nihill), D.D., a native of Tulla, County Clare.^[1]
