You're perfectly right! Giuseppe Sultana was my great great grandfather. My greatparents lived in Gajdoru st. Now my uncle and my aunt live in that street too. So the name has returned back to its origins.
Do you know anything about the family before 1939 please?
Also the name Silvestro did run in the family. Giuseppe's father's name should be Silvestro. They wanted to name my grandfather Silvestro too but did not do so due to a suggestion by the priest on the name Emanuel.
