Giuseppe Gerardo Gallone.

Giuseppe Gerardo Gallone is born in 1766, the same year as the death of his father, the 5th Prince of Tricase Giuseppe Domenico Gallone (1706–1766). He therefore grows up under the maternal guardianship of Beatrice Sersale (1737–1786), of the Marchesi Sersale, until reaching his majority. He inherits, besides the princely title, that of 12th Baron of Specchia Gallone.

After his emancipation, Giuseppe Gerardo restores the financial agencies of the house — essentially lending activities to the great Neapolitan Houses — which had constituted an important part of the Gallone patrimony since the 17th century.

In 1796, in second marriage, he marries Maria Emanuela Pignatelli (1775–1818), daughter of Giovanni Battista III Pignatelli, prince of Moliterno and Marsiconovo. He concludes mortgage contracts on the goods of her brother, Girolamo III Pignatelli (1773–1848), 3rd Prince of Moliterno and 5th of Marsiconovo, laden with debts and fallen into political disgrace.

By this route Giuseppe Gerardo recovers the fiefs of Moliterno and of Marsiconovo with the attached princely title. It should be noted that the formal title of Prince of Moliterno would be officially devolved to the House of Gallone only in 1848, on the death of Girolamo, with his son Giovanni Battista, 4th Prince of Moliterno and 7th of Tricase: Giuseppe Gerardo himself thus remains remembered mainly as 6th Prince of Tricase.

In a draft petition to the king, Giuseppe Gerardo states that his ancestors served the Angevins as early as 1284 and then the Aragonese, that the proofs are preserved in the Grand Archive of the Regia Camera della Zecca of Naples, and he asks to be admitted "among the gentlemen of the Chamber in office".

From the marriage with Maria Emanuela are born five children: four daughters (Beatrice, Maria Luisa, Brigida, Michela) and the only son, Giovanni Battista Gallone (1800–1868), heir of the house and future 7th Prince of Tricase, 4th Prince of Moliterno on the death of his uncle Girolamo in 1848. The youngest daughter Brigida dies around 1806, at about one year of age.

Giuseppe Gerardo dies in 1806, at forty. He is buried in Naples in the chapel of the Immaculate, under the juspatronage of the Gallone family, in the basilica of San Pietro ad Aram, where his daughters and his wife Maria Emanuela would later also be buried.

In Tricase, in the two altars of the transept of the mother church — dedicated to the Virgin of Constantinople and to Saint Charles Borromeo, already under Gallone patronage — is found the impaled Gallone-Pignatelli coat of arms in inlaid polychrome marble, a lasting memory of the 1796 marriage.
