Hi Krista
I would check this 1873 map with homesites.
http://www.historicmapworks.com/Map/US/3488/Wheeler/
Or if you like,check out the entire 1873 Steuben atlas here

To zoom in really close you may have to create an account on historicmapworks. It is free though. I was just using one of the maps I printed out from their site this weekend while detecting.
this map is nice also but not as detailed
