In the county-history sources
5,852 words on this townshipHistory of Mercer County, Ohio, and Representative Citizens, published 1907 names this settlement in its chapter on Dublin Township. These are the passages that mention it, exactly as the scans read.
The township has two railroads. The Cincinnati Northern, which has for its southern terminus, Cincinnati and for its northern, Jackson, Michigan, passes through Rockford, which is the market for the entire northern part of the county and the only town of any importance in the township. A branch of the Cincinnati, Hamilton & Dayton Railway passes through Mercer, a settlement in the southeastern corner of the township. This section of the county is, therefore, afforded good shipping facilities. The first railroad built in the township was the old Toledo, Delphos & Burlington Railroad, a narrow-gauge line, from Delphos to Rockford by the way of Mercer, with the main line running from Delphos to Dayton, via Celina. In a few years, however, the branch froni Mercer to Rockford was abandoned. Tbe main line at a later date was absorbed by the Cincinnati, Hamilton & Dayton Railway and became a standard-gauge road.
