Donald Robert Perry Marquis, don marquis, marquess.
I had occasion to remark that when those Roman princes were presented at the court of France they were only styled " marquis:" It was the same with the Russian princes, to whom the title of prince was refused when they wanted to be presented; they were called " knees," but they did not mind it, because that word meant prince.- "The Memoires of Casanova, Complete The Rare Unabridged London Edition Of 1894, plus An Unpublished Chapter of History, By Arthur Symons", Jacques Casanova de Seingalt.
