Simon Guerri dall'Oro Gallone.

Simon is in union with Coline Morel, b. in Besançon on 29 March 1986 (civil partnership celebrated in Sydney on 17 November 2017). From their union, two children: Léon Guerri dall'Oro Gallone, b. in Sydney on 10 March 2018, future 13th Prince of Tricase and 10th Prince of Moliterno; and Auguste Guerri dall'Oro Gallone, b. in Geneva on 24 January 2021.

By the Decree of the Minister of Grace and Justice of 21 January 1999, the full surname Guerri dall'Oro Gallone di Tricase e di Moliterno is transmitted to the descendants of Count Aldo and Donna Simonetta. Simon is, in the direct line, the twelfth holder of the Principality of Tricase since the 1651 grant to Stefano II Gallone — in conservation of the honorific title through the Neapolitan Female Succession (see Legal note on the Regio Assenso).

The site principeditricase.com is the publication, in the public domain, of a portion of the genealogical research conducted by his father Guido over more than twenty years — itself founded on the archival work of his grandfather Aldo. Simon ensures its digital transposition, multilingual translation (Italian, French, English, Spanish) and dissemination.
