His appearance in some important Scottish appeal cases brought him into notice, and in Scotland at least he acquired an immense reputation by his appearance for the city of Edinburgh when it was threatened with disfranchisement for the affair of the Porteous mob.
JOHN PORTEOUS (d.
1736), captain of the city guard of Edinburgh, whose name is associated with the celebrated riots of 1736, was the son of Stephen Porteous, an Edinburgh tailor.
Porteous, who was said to have fired at the people with his own hand, was brought to trial and sentenced to death.
The incident of the Porteous riots was used by Sir Walter Scott in The Heart of Midlothian.
