Philip,
In the Ripley County History Book 1818-1988, there is an article about
Shockley School #12 which gives the school's location as "East of Milan across
from
the Mary Ashcraft property, near the Shockley Cemetery, just north of Indiana
350." Indiana 350 runs through Milan east and west, so I'd guess if you can
get to Milan or find someone from Milan, you're pretty much home free for an
exact location.
