Tony: The closest map to that time period with names of landowners on it would be the 1881 Standard Atlas of Wayne County. They have a copy at the Fairfield Public Library. I have a copy of the Indian Prairie page and don't see the Wickersham name at a quick scan. When did they leave the area? My great great grandparents are buried in Johnsonville Cemetery too.
