Prince Carlos of Bourbon-Two Sicilies: Don Carlos, Prince of Bourbon-Two Sicilies, Infante of Spain (Full Italian name: "Carlo Maria Francesco d'Assisi Pasquale Ferdinando Antonio di Padova Francesco de Paola Alfonso Andrea Avelino Tancredi, Principe di Borbone delle Due Sicilie, Infante di Spagna"; 10 November 1870, , Bolzano, Italy – 11 November 1949, Seville, Spain) was the son of Prince Alfonso of the Two Sicilies, Count of Caserta and his wife Princess Maria Antonietta of Bourbon-Two Sicilies, and nephew of the last King of the Two Sicilies, Francis II.

Umberto II of Italy: Umberto II (Italian: "Umberto Nicola Tommaso Giovanni Maria di Savoia" ; 15 September 190418 March 1983), was the last King of Italy.

List of marquesses in Italy: Italy, as a single nation state, began only in 1861, after the Piedmont-based Kingdom of Sardinia conquered most of present-day Italy.  At that point, titles were recognized to all who held them according to the law of so-called "pre-unitarian" States.  Consequently, the Kingdom of Italy had several different nobility traditions, one for each pre-unitarian State and one for the unified state (that was actually the Piedmontese-Savoyard one).  That is why the Italian College of Arms, called "Consulta araldica" (heraldic council), was organized in 14 "regional" commissions.  Common rules concerning all titles were established only in 1926.  That is why a list of Italian marquisates has to be divided into different pre-unitarian lists, plus a unified list for titles granted after 1861.  The latter should be completed with titles granted by the last King of Italy, Humbert II, during his exile and after the proclamation of the republic (1946), until his death in 1983: these concessions base upon the fact that he was not defeated in war and thus remained a king, that is a "fons honorum", but this issue is controversial, titles granted by a non-reigning king not being recognized by most noble and royal families in Europe.  Only the Sovereign Military Order of Malta and the Corpo della Nobiltà Italiana recognize these titles, while the CILANE treats them as mere titles of courtesy.
