Church of St Mary, within the Castello, where survives his elaborate monument erected by his son and successor William. 1839–1872: William Thovez ("son" of William Thovez) incontrastato padrone ("undisputed boss"), who effectively ruled the duchy for 33 years and due to his office was "one of the most powerful and wealthy men in the whole Province of Catania" and was the head of the ducal faction during politically turbulent times, most notably during the uprisings of 1848 and 1860. He features in the 1972 film by Vancini, meeting with General Nino Bixio, sent by Garibaldi to quell the 1860 uprising and massacre. He married twice, firstly to Rosaria Fragalà (1808–1856) whose elaborate monument survives in the Monastic Church of St Mary, within the Castello, and secondly he married (in the 5th Duke's words) "An unpleasant English woman, governess of his daughter, who played her role in the origin of the big disagreement".
