These are my relatives Benko and Stella Darsi. She was a Kalef before she married. She is my granduncle Avram Kalef's daughter from his first marriage. It is a good thing I wrote down his name ten years ago. By now I would have forgotten it. They lived on Visokog Stevana Street in Dorcol, Belgrade. Here it says: ?Kalef - Stella and Bobenko?
