Isak Benvinisti's family

This is a picture of the family of Isak Benvinisti, the brother of my father Mair. The photo was taken during the Holocaust in 1944 when all Jews used to wear badges. His wife Perla is on his left. She married him, despite the fact that she was his first cousin. That's why their children were not quite of sound mind. I think that's the reason why Aunt Perla became mentally ill, and I think she took her own life. In any case there was a great tragedy in that family before their leaving for Israel. I recall that at the time when this picture was taken, their family lived with us on 16 Bratia Miladinovi Street in Plovdiv. Uncle Isak went to Israel only with his children. I don?t remember their names.
