Sergiy, it is so nice of you to help me!
My cousin from Israel was in contact with people from Nikopol a few months ago. These women who were teachers are probably dead by now, and my cousin thinks that one of them probably went to the US or Israel, but since she was married, we cannot find her by her maiden name.
The other lady never got married, so she was a KHINKIS when she died...her name was Anna. We don't know the name of her sister.
