The only reminders of the Joseph Martin family, black settlers from Illinois, is found in this little half-acre burial ground south of St. John. Approximately 20 people are buried here, with only a few marked graves dating from 1906 to 1954. Drawn by the promise of good land and unlimited opportunities, the Martin group arrived here circa 1878, just prior to the vast Exoduster migration to areas in eastern Kansas. (NRHP)
