Charles Mahoney was an Irish Franciscan friar and priest who lived during the 17th century. Born around 1640 in the Kingdom of Ireland, he traveled to Rome to study at Saint Isidore's College. After being ordained on the European continent, he attempted to return home but was shipwrecked during the journey. Following his arrival, he was arrested in 1678 and held in Denbigh before being tried in Ruthin, Wales, where he was executed by hanging.
