My daughter has been activity tracing the family tree. She has found many relatives even my father, David Imber, did not know about. My father, who passed away in Aug 2004, was a nephew ( we think) of Naftali. My grandmother would not allow his name mentioned in the house when my father was a child as he was "the black sheep of the family" He was an alcholic and a Zionist. That was way before the poem became the national anthem of Israel. I am going to pass your email on to my daughter and I am sure she will write to you.
