We also have Family Maps of Iowa County, Wisconsin by Gregory A. Boyd. This 370 pages book is packed with 86 maps. It contains maps of original landowners (patent maps) in what is now Iowa County, Wisconsin, gleaned from the indexes of the U.S. Bureau of Land Management. For each township in the county, there are two additional maps: a road map and a map showing waterways, railroads, and cemeteries.
