I moved this discussion on to the Nobles County Yahoo Groups website in hope that others will contribute to the list. I hope that is OK with you.
Your input so far was just what I had in mind when I asked you about
any buildings. This will be a great help. What do you know about the
houses on 8th Street by the antique shop including the antique shop.
Did any of them have a local historical figures associated with them?
I was also thinking about Rezeau Plotts's house on Okabena Street, I would think this would fit.
