Zalman, you know her parents names, first and last? You know her given name, year and place of birth? No one in her immediate family knows her whereabouts? Using her full maiden name should be a start in Google, Facebook and all the genetic websites.
DNA testing might help find a wide circle of relatives.
You could post all the information you know here, and maybe someone knows of her. We are all stuck at home looking for projects!
