During WWII my family lived next to "Moon's Grocery Store" in Platteville. I remember Mr. Moon as being a wonderful, kind, & happy fellow. Could he be related to your Moons? Don't remember his first name. Maybe there is some info on this family at the Wisconsin Room, at the Karmann Library, which is located on the campus of the UW-Platteville. A bicycle shop is now located where the old Moon's Grocery was located. And is next door to the Brick School. Good Luck in your search.
