You may be interested to know that a descendant of Baldassare Viscardini, who was an immigrant to Britain and a cabinet maker in London by 1881, also changed his name to Carden in the 1920's. I have always supposed he chose the name because there was a prominent Carden family living nearby, but I wonder if Calderone and Viscardini knew each other and influenced the choice of name. I will be glad to provide more information on request.
