JOANN LEWIS was living at the MN orphanage in Owatonna ( a town near Mankato). From there she was 'farmed out' to a smaller town named Nicollet. Nicollet had a very small school, everyone from K-12 was in the school. The school was named Nicollet High. She graduated in the year 1949. I would check anywhere from 1945-1949.
