Regina Eskenazi and her family

These are my cousins. This is Regina Eskenazi (nee Kalef) who went to Israel with her husband, Isak, and children. Their boys are Avramce and Marsel. I would so like to know what happened to them and where they are. They contacted us once more after this photo was taken in 1948, and then that was it. I don?t know how they met. Her husband was Bulgarian. During the war they were in a camp in Bulgaria but the camp wasn?t liquidated. I think that they left Israel and went further, maybe to America.
