Prior to the 1967-68 school year, a committee was formed of 24 students (one boy and one girl from each of the four classes at Royerton, Eaton and DeSoto). These students were tasked with selecting a name for the new school, as well as a mascot, colors, and a song.
Several names were discussed, including Nor-Del, Grissom, and Apollo. Nor-Del was rejected because there already was a Wes-Del nearby. Grissom, in honor of Hoosier astronaut Gus Grissom who had died in a fire, was given strong consideration, but the committee then learned there already was another Grissom in Indiana. Apollo was another idea to honor the burgeoning space program.
One of the 24 committee members, Dale DeHaven, a freshman from DeSoto, then suggested Delta. DeHaven said he came up with Delta by playing around with letters that were common to the three consolidating schools, Eaton, DeSoto, Royerton, and the word Delaware.
