Florian ancestors in New Prague and St. Paul, MN area

I am searching for pictures of Jacob and Marie Florian who lived in Union Tsp, Worth County about 1876-1883), Helena Tsp, Scott County (1884-1895), West 7th St area of St. Paul, MN (1895-1917). I have a picture of Marie but would love to find a photo of Jacob. He was a farmer in the New Prague area. He died in 1897 at 192 Duke St. Paul, MN. Any ideas where I might look or other help would be greatly appreciated. It is hard to believe that one of his 9 children Anna, Mary(Schneider), Katherine(Snell), Elizabeth(Misera), James, Louisa(Keegan), Theresa(Hover), Christina Lipold) and Rosa(Noska) didn’t have a picture of their father Jacob passed down to descendants.

Thanks.
