Unfortunately, my book about Goodhue Co. does not contain an index to every surname it contains. There is an Index to Biographical Sketches that lists prominent members of Goodhue Co. I was unable to find any Zimmermans or Smiths in this index. I also read the chapter about Red Wing and didn't find either of these names. Winona is in Winona Co., so the Civil War records would not be in my book. Sorry I couldn't be of more help. Good luck in your research.
