The Giustiniani family were a powerful nobility of Venice and Genoa involved in the Roman Catholic Church, Venetian politics, and merchant banking. The Giustiniani family produced Doges for Venice and were members of the Council of Ten. Many North Italian banking families from Venice, Genoa, and Florence reestablished themselves in the Holy Roman Empire. I believe that the British Rothschild branch is closely related ancestors of the Bardi banking family of Florence that funded the King of England with 900,000 gold florins which was never repaid. The British Rothschild are financiers for the British Crown today just as the Bardi family financed the English Crown. The wealthy Mars family is the continuation of the Candia family of Venice.

The Fugger and Welser banking families appear to be closely related to the Giustiniani and Foscari families and likely other merchant banking clans from Northern Italy. The two families built palazzos next to each others on the Grand Canal in Venice. The Italian word Giusto means "good" "right" or "well". The German phrase Fug und Recht means good and right. Fug also means fog or daze similar to the Italian word fosco which means dark or cloudy. Fosco like Foscari and they were another powerful Venetian family that ruled as Doges in Venice and were members of the Council of Ten. The Fuggers were extremely wealthy bankers that intermarried with German and Austrian Nobility. The Welsers were another powerful banking family. Both families established themselves in Augsburg Germany. The Welsers used the Fleur-de-lis on their coat of arms which also suggests a possible Florentine ancestry. Prince Hubertus Fugger-Babenhausen is the head of the Fugger family today.

All of these families were branches of North Italian bankers and merchants and especially the Giustiniani fand Foscari families. Wells Fargo is a continuation of the Venetian bankers. Guisto, Wells, Welser, and Fug all have the same meaning of well or right and all are connected with banking. The Fugger family appears to be mostly related to the Foscari family. These families establish banks and then finance and control other family branches which evolve and blend into other regions and people. Today Alessandro Giustiniani is a senior economist that has worked with the International Monetary Fund in Washington DC and also for the Bank of Italy in Rome. Baron Girolamo de Massa is the head of the Venetian Giustiniani family. Baron Girolamo de Massa is a really a Massimo-Giustiniani and is involved in overseeing Wells Fargo. In Rome there is a Villa Giustiniani Massimo.
