I've always been told my great grandparents original spelling of their last name was Sywyk but just recently found a booklet that had the name spelled Siwik. I think it was after he came to the USA. I would love to get ahold of you or any one with this last name from the Ukraine. They lived near the Poland border. I am originally from Michigan and I know my great grandparents lived in Chicago at one point. Not much else!
