McGuckin, James, attorney, south parade, Here was one of the most despicable men that ever lived in Belfast, he was one of the defence attorneys working in the trial of William Orr, and close associate of the leadership of the United Irishmen, and yet he was a long term paid informer. McGuckin was a Catholic and became a staunch and respected member of the Catholic Society and carried out his profession in Belfast until his death.
From "Belfast 1807" by Joe Graham.
