John Leslie (bishop of Kilmore, Elphin and Ardagh)

[2] His great-grandfather was Charles Leslie, a noted Non-Juror member of the Church of Ireland and one of the most prominent Jacobite propagandists after the 1688 Glorious Revolution.

The Leslies were a numerous and prolific family with a long history of service in the Church of Ireland; his great-grandfather was Charles Leslie, a noted Non-Juror member of the Church of Ireland and one of the most prominent Jacobite propagandists after the 1688 Glorious Revolution.

Born 12 October 1772 on the family estate at Glaslough, County Monaghan, John married Isabella St Lawrence (1790-1830), daughter of Thomas St Lawrence, Bishop of Cork and Ross and his wife Frances Coghlan, and granddaughter of the 1st Earl of Howth, and they had eight children.

In 1819, his elder brother Charles, a prominent supporter of Lord Liverpool's government unsuccessfully petitioned for him to be made Bishop of Clogher, which included the family estate at Glaslough.

His son Charles Leslie was also briefly Bishop of Kilmore, Elphin and Ardagh; he was enthroned on 24 April 1870 but died a few months later on 8 July.
