Voronetski is my great-grandmother's maiden name. I was told that she was Polish, but that is not definite. She lived in the southern part of Ukraine (small town called Balta or Bulta, half a day on the train north from Odessa), but she moved there(was born elsewhere). Her moving must have happened before 1937 (that's when my grandmother was born), so I am wondering about her possible background and ethnic origin, as well as of the name itself. I would appriciate any related info.
