2. Indian Agency House Marker
In all probability, our missing marker was once situated right where this present day marker is currently situated. It seems like the present day Ohio Memorial markers often have replaced missing, 1930 era, Ohio Revolutionary Memorial Commission markers.
More about this marker. This historical marker is part of the Ohio Revolutionary Memorial Trail series (type C) which was put in place in 1930 to celebrate the 150th anniversary of the Ohio's Revolutionary War era Battle of Piqua, by the Ohio Revolutionary Memorial Commission.
In order to accomplish this, in 1929 the state of Ohio created the Ohio Revolutionary Memorial Commission, and then in 1930 this commission created 22 military trails, throughout western Ohio, between Cincinnati, Ohio on the state's southern border and Toledo, Ohio on the state's northern border. Each of these military trails represented the routes, or trails, used by military leaders during either the Revolutionary War, the Indian Wars of 1790 to 1795, or the War of 1812. Each of these military routes connected various related historical sites, that were marked with Ohio Revolutionary Memorial Commission (type C) markers, along each of the military trails.
The routes of these military trails were in turn marked by type A and type B Ohio Revolutionary Memorial Commission markers that served as directional (type B) and distance (type A) markers.
Originally, back in 1930, there were erected 70 some of these Ohio Revolutionary Memorial Commission, type C, markers. To date, there are only 20 some of them that have been located and posted on the Historical Marker database. A number of them are presently missing, including this particular marker, which is listed on page 74 of the ORMC 1931 Planning Report.
