The Garden Of The Finzi-Continis

Does anyone know if the family (of the Finzi-Contini) were a real family or were they ficticous?

The film by Vittorio De Sica was based on the novel by Giorgio Bassani, published in 1962. I fear that the key word here is novel. Although fiction he has tried to show the real life that the Jews in Italy suffered during the Second World War.

The film of course won the Oscar for Best Foreign Language Film
