Looking for possible high school records, if they exist in Superior, for my grandfather. Born in 1888, he may have graduated around 1906 or '07. His older sister, in a narrative she wrote about her early years, mentioned that she attended Howe Grade School, Blaine Grade School, and then High School (but no name attached to the H.S.). Does anyone have an idea of which high school might have been operational at the early part of the century, and if records of graduations still exist?
