I found a testemony in Yad va Shem about the brother of my GF's family (attached by).
My GF testified that Abraham Slomo was murded in the Iasi trains (1941).
Abraham was his father's name and it became his family name.
We do not find what happened to his wife, Bracha, and one of his children.
About the second child, Pesia, there is a testemony that she was killed in Aushwitz.
I will be happy to find if they servived or what happened with them.
