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.
