In 1811, Jocelyn's brother John's coachman, James Byrne, accused him of "taking indecent familiarities" and of "using indecent or obscene conversations with him". Byrne was sued for criminal libel by Jocelyn and on conviction was sentenced to two years in gaol and also to public flogging. After he recanted his allegations at the prompting of the bishop's agent, the floggings were stopped. On 19 July 1822, Percy Jocelyn was caught in a compromising position with a Grenadier Guardsman, John Moverley, in the back room of The White Lionpublic house, St Albans Place, off The Haymarket, Westminster. He and Moverley were released on bail, provided by the Earl of Roden and others. Jocelyn broke bail and moved to Scotland where he worked as a butler under an assumed name. He was declared deposed in his absence by the Metropolitan Court of Armagh in October 1822 for "the crimes of immorality, incontinence, Sodomitical practices, habits, and propensities, and neglect of his spiritual, judicial, and ministerial duties". A public subscription was raised to raise money for James Byrne, whose 1811 conviction was now recognised as a miscarriage of justice. Jocelyn was the most senior British churchman to be involved in a public homosexual scandal in the 19th century. It became a subject of satire and popular ribaldry, resulting in more than a dozen illustrated satirical cartoons, pamphlets, and limericks, such as: The scandal was so great, that in the days following, "it was not safe for a bishop to show himself in the streets of London", according to Charles Manners-Sutton, Archbishop of Canterbury at the time. In August 1822, Robert Stewart, Viscount Castlereagh, who was both the Foreign Secretary and Leader of the House of Commons, had an audience with King George IV where he said that he was being blackmailed, and that "I am accused of the same crime as the Bishop of Clogher." He committed suicide shortly afterwards, and was thought to have been in a paranoid state at the time.
Legacy
Reports differ as to where Jocelyn is buried. It has been widely assumed that he died and was buried in Edinburgh under the assumed name Thomas Wilson, with the following inscription : "Here lie the remains of a great sinner, saved by grace, whose hopes rest in the atoning sacrifice of the Lord Jesus Christ." However, some years ago the Jocelyn family vault in Kilcoo Parish Church in Bryansford, County Down, Northern Ireland was opened and it was discovered that it contained one more coffin than the number of grave markers indicated, and that the extra coffin was unmarked. This extra coffin may be that of the Bishop of Clogher. For 178 years after the scandal the Church of Ireland refused to let historians see its papers on the affair. In the 1920s Archbishop D'Arcy of Armagh ordered that they be burned, but this order was not obeyed. The files were released for Matthew Parris's research for his book The Great Unfrocked.
