Catholic Encyclopedia (1913)/Ferdinando d'Adda
Cardinal and Papal Legate, b. at Milan, 1649; d. at Rome, 1719. He was made Cardinal-Priest in 1690, and in 1715 Cardinal-Bishop of Albano. He was also Prefect of the Congregation of Rites. As Papal Nuncio in London during the reign of James II (1685-88) he was charged by Innocent XI with the delicate task of inducing the English King to intercede with Louis XIV (then quite inimical to the Holy See) in favour of the oppressed Protestants of France.
