Maria Bianca Gallone.

Maria Bianca is born in Paris in 1895, in circumstances marked by a scandal that stirred the Naples of the time. Her mother, the princess Giuseppina Moncada of the Princes of Paternò, was then married to Nicola Gaetani, Duke of Laurenzana; her liaison with Pietro Giovanni Battista Gallone, 9th Prince of Tricase, could therefore not be openly acknowledged.

To shield the birth from Neapolitan clamour, Giuseppina gave birth in Paris and the birth certificate was drawn up without the mother's name: Maria Bianca thus came into the world as a natural daughter, formally without maternal filiation.

On the death of Nicola Gaetani, Duke of Laurenzana, Maria Bianca's parents could at last unite in a formal marriage (1924). This marriage produced the legitimation by subsequent marriage, an institution which, with ex tunc effect, retroacts to the birth: Maria Bianca was thus recognised in all respects the legitimate daughter of Pietro Giovanni Battista Gallone and of Giuseppina Moncada, and therefore fully inserted into the line of succession of the House of Gallone.

On the death of her father, in 1931, she became 10th Princess of Tricase and 7th Princess of Moliterno, last direct holder of the house.

Maria Bianca married Augusto III della Posta, 7th Duke of Civitella Alfedena. From their union was born the only daughter Simonetta della Posta (1916–1986). With Maria Bianca the direct descent of the Gallone becomes extinct: it is therefore through her and her daughter Simonetta that the predicate passes to the della Posta line and, through Simonetta's marriage to Aldo Guerri dall'Oro (1939), to the House of Guerri dall'Oro.

This passage would finally be sanctioned by the Decree of the Minister of Grace and Justice of 21 January 1999, which recognises to the descendants the surname Guerri dall'Oro Gallone di Tricase e di Moliterno. Maria Bianca is thus the pivot of the transmission between the ancient princely house and the present-day family.

In the 1950s, after selling all the goods — including the Palazzo Gallone, the 17th-century castle of Tricase — Maria Bianca became municipal councillor, the first woman in the history of Tricase. She died on 24 July 1982. The local press hailed her as "the last of the Gallone".

On 4 June 2026 the remains of Maria Bianca and three of her kin were translated from the old cemetery of Piazza Cappuccini, now disused, to the Confraternita di Maria SS.ma Immacolata di Sant'Angelo, in Tricase. Alongside her now rest her father Pietro Giovanni Battista «Gino» Gallone, 9th Prince of Tricase, her mother Giuseppina Moncada of the Princes of Paternò and Antonietta Melodia of the Barons of San Pietro in Melicozza, wife of Giuseppe Gallone, 8th Prince, and paternal grandmother of Maria Bianca.

The translation took place with the consent of the descendants, for the Nobili Vitelleschi branch (Francesca, Giacinta, Fabrizia and Sinibaldo) and for the Guerri dall'Oro Gallone branch (Simon, 12th Prince, Eleonora and Emanuela). The initiative is owed to Andrea Bentivoglio, his sister Betty and Mario Turco; the blessing was given by Don GianLuigi Marzo.
