The most well known of the Hell Fire Clubs was the Order of St. Francis, named after their charismatic founder Sir Francis Dashwood, member of Parliament and a Freemason. Dashwood, along with eleven others (collectively dubbed the Unholy Twelve) founded their club sometime in the mid 1740’s. From 1750 they met at a disused Cistercian abbey at Medmenham. Meetings began with a black mass and ended with an orgy with a variety of other dubious entertainments in between.
