Glasgow's Episcopal clergy had been operating outside the law (non-juror), but in 1712 a clergyman arrived prepared to take the oath to make him 'qualified'. William Cockburn set up a meeting-house (he calls it a chapel); the location is not recorded. In 1713 he also marked the death of Charles I. His sermon on that occasion survives, with a list of the congregation, which includes established Glasgow families such as the Bells, Barns, Crawfurds, Grahames, and Walkinshaws, and Alexander Duncan. Sir Donald MacDonald of Sleat played an important part, and his Highland retainers, Gaelic-speaking and in kilts, acted as guards. This chapel was attacked by a rabble a few days after Queen Anne's death and Cockburn fled, an event commemorated in an anonymous ballad, "The Downfall of Cockburn's Meeting House", found amongst Wodrow's papers.
