I love maps and have been trying to find this particular one for quite some time. I owe a big thank you to Gary Jacobson for allowing me to copy his copy of the map. If you have been trying to find the 1879 Steele County Minnesota Plat map, his site does a great job with it.
Here’s a copy of the map:
If you click on the map and look in sections 19 and 20 you can see the two parcels owned by W.R. Knickerbocker in 1879. This is a copy of the 1879 Plat map of Somerset Township, Steele County, Minnesota. For more information on what a Plat map is, the Wikipedia entry has some nice information.
