your post is more than a decade old, but on the chance you are still active in the genealogy community I might respond.
I am descendant from this line of Smiths. Henry Smith (born in Winneshiek), later settling on Turkey River in Howard County, would be my great grandfather.
Do you have more information on the family?? I have been desperately trying to get any information, but especially photographs.
