Count Sesto is the title borne by the current head of the existing noble family of that name, of ancient Genoese and subsequently Sicilian origin.
The current comital family, through marriage and inheritance, established itself in the Kingdoms of Naples and Sicily, first in the area of Salerno and later in Sicily, in the area of Messina, over time being known as Sesto, derivation of the original familial title.
In 1711, following the death of Don Gaetano Pinelli, Duke of Acerenza, Marquess of Galatone and Count of Copertino, and concomitant with the arrangements which led to the succession of Oronzo Ravaschieri Fieschi Pinelli, 5th Prince of Belmonte to the titles of Duke of Acerenza, Marquess of Galatone and Count of Copertino, the last two titles being created in 1562 for the Squarciafico family, the Sesto line, allied by marriage to the Squarciafico family since the marriage of Giulio Cesare, 2nd Marquess of Galatone to Lelia Spinola, daughter of Filippo Spinola, Duke of Sesto and Marquess of Venafro, was granted the title of Count in the Kingdoms of Naples and Sicily by Philip V of Spain (Philip IV of Naples and Philip IV of Sicily).
The grant was accompanied by feuds and estates at Castroreale, Barcellona and Novara in the Province of Messina.
The current head of the comital family, Count Cesare Filippo Ambrogio Sesto lives in Tuscany.
