Top on my list are these pictures of John Marshall school. It was located on County V in the Town of Fond du Lac, and this is the school where my dad and all his siblings got their education.
I have looked for a picture of this school for years!!!
Another school picture I found today, was the Nels Anderson School. This was in section 2, Township of Byron.
The following two pictures were just labeled "Estabrooks School"
Finally, the picture of this small building was labeled as being the school near Empire Cemetery. Not sure what it's name would be, but it is probably Hill Crest School.
