In section 20 of South Union Township, there was a school called Willow Grove (school township 27). If the school was still standing it would be on the East side of 231 S after 300 South and prior to Evergreen Nursery. (This photo was property of Ben Miller, the last boy on the front row, who is holding the sign). Mr. O.W. Oliphant is the teacher.
Thanks to John M. Merrell for allowing us to scan the picture.
