I found more info since my last response to your posting. There was a school in Sawyer Co. called Munger School, so named because there were two or three families by that name living in that neighborhood. It was located in the NW corner of the NW1/4 of the NE1/4 of Section 8, Township 41, Range 9 (see this plat map at http://www.rootsweb.com/~wisawyer/platmaps/sc41n9w.htm
- you will see the notation of the school (SCH) in section 8, just south of the township line at the above stated location). None of these Munger families were living in this area as of 1902. The school was a small frame building built during the fall of 1889. A listing of the teachers and school terms can be found here - http://www.rootsweb.com/~wisawyer/schools/munger.htm
The above information came from the book "History of Education in Sawyer County Wisconsin, 1902", page 200.
There is also a short biography of Joseph F. Munger which I will be posting separately on this message board.
Again, I hope this info is of help to your research.
