The church at Derrykeighan was founded by St. Colman in the fifth century. Old headstones from the seventeenth century have been built into the walls of the ruins. United Irishmen Francis McKinley and William Dunlop were buried here following their execution for their part in the ill-fated rebellion of 1798. John Meeke MM (military medal), a World War One hero, is also buried in the graveyard. Meeke risked his life to save William Redmond, a famous Irish Nationalist MP, who had been injured on the battlefield.
