Leonardo IV Tocco, that the Tocchi again became landed nobles as he was granted the fortress Refrancore in Piedmont by Constantine, ruling it with the title Lord (signore). Leonardo IV's grandson, Leonardo V Tocco, added to the family lands by purchasing the barony of Apice in 1639. Leonardo V's son, Antonio, who abandoned the despotal title, also increased the number of territories held by the family significantly. In 1665 he purchased the barony of Calabritto and in 1674, Antonio inherited the titles Prince of Montemiletto, Count of Monteaperti and Baron of Grumo, Montefalcione, Serra and Manocalzati from his father-in-law. From Antonio's time and onwards, the Tocchi mainly identified themselves through their ownership of Montemiletto. Antonio's grandson, Carlo Antonio Tocco, purchased the baronies of Nocelle and Fontanarosa, but sold the Barony of Calabritto. Carlo Antonio's son, Leonardo VII Tocco, was made Duke of Apice in 1720, and would serve the Papal States and the Holy Roman Empire in high positions.

Restaino's son and heir, Carlo II di Tocco Cantelmo Stuart, gained the title Baron of Roccavallescura and of Pratola. The Tocco family went extinct with the death of Carlo's grandson of the same name on 24 March 1884. This Carlo di Tocco Cantelmo Stuart, and his father Francesco before him, had been the leader of a faction of Bourbon legitimists who wished to restore the Kingdom of the Two Sicilies after the formation of the Kingdom of Italy in 1861.
