Don Jacob Casanova, the illegitimate son of Don Francisco Casanova, was a native of Saragosa, the capital of Aragon, and in the year of 1428 he carried off Dona Anna Palofax from her convent, on the day after she had taken the veil. He was secretary to King Alfonso. He ran away with her to Rome, where, after one year of imprisonment, the pope, Martin III., released Anna from her vows, and gave them the nuptial blessing at the instance of Don Juan Casanova, majordomo of the Vatican, and uncle of Don Jacob. All the children born from that marriage died in their infancy, with the exception of Don Juan, who, in 1475, married Donna Eleonora Albini, by whom he had a son, Marco Antonio. In 1481, Don Juan, having killed an officer of the king of Naples, was compelled to leave Rome, and escaped to Como with his wife and his son; but having left that city to seek his fortune, he died while traveling with Christopher Columbus in the year 1493. Marco Antonio became a noted poet of the school of Martial, and was secretary to Cardinal Pompeo Colonna. The satire against Giulio de Medicis, which we find in his works, having made it necessary for him to leave Rome, he returned to Como, where he married Abondia Rezzonica. The same Giulio de Medicis, having become pope under the name of Clement VII, pardoned him and called him back to Rome with his wife. The city having been taken and ransacked by the Imperialists in 1526, Marco Antonio died there from an attack of the plague; otherwise he would have died of misery, the soldiers of Charles V. having taken all he possessed. Pierre Valerien speaks of him in his work ‘de infelicitate litteratorum’. Three months after his death, his wife gave birth to Jacques Casanova, who died in France at a great age, colonel in the army commanded by Farnese against Henri, king of Navarre, afterwards king of France. He had left in the city of Parma a son who married Theresa Conti, from whom he had Jacques, who, in the year 1681, married Anna Roli. Jacques had two sons, Jean-Baptiste and Gaetan-Joseph-Jacques. The eldest left Parma in 1712, and was never heard of; the other also went away in 1715, being only nineteen years old. This is all I have found in my father’s diary: from my mother’s lips I have heard the following particulars: Gaetan-Joseph-Jacques left his family, madly in love with an actress named Fragoletta, who performed the chambermaids. In his poverty, he determined to earn a living by making the most of his own person. At first he gave himself up to dancing, and five years afterwards became an actor, making himself conspicuous by his conduct still more than by his talent.
