Miller Grove ~ In the 1840's a community of emancipated families from Tennessee bought land north of present day Glendale, and began a farming community that became known as Miller Grove. The community built a church and a school. A large cemetery holds over one hundred graves, many unmarked and some with tombstones (most now a days unreadable). Archaeological investigations are continuing at this site which now lays within the Shawnee National Forest. It will eventually be an interpreted site open to visitors. I will add the coordinates to the settlement once I have the exact location confirmed, however, there is nothing left standing at the settlement that I am aware of.
The SNF visitor centers have a brochure on " African American Settlements in Southern Illinois" for the asking.
