Zadra would seem typical of the CE area includes Trento, Cles and Tres, Zadro, much rarer, has a nucleus between the provinces of Pordenone and Venice, zone of San Vito Al Tagliamento and Cordovado (PN) and Portogruaro (VE), should derive from a dialect nickname Derived from the dialect word Zadro (theatre) derived in turn from the Latin word Theatrum, originated the nickname probably from inhabiting the family in the vicinity of a place where they held theatrical performances. Traces of these cognitive references we find in Treviso in 1368 with the notary of the lower chancellery of the Serenissima Republic Girolamo Zadra, and in Pozzolo (VI) in 1500 with a certain Giorgio De Zadra quoted in an act of 1542.
