According to the Centennial Atlas of Athens County (1905), the community originally called Canaanville was slightly to the west, west of where Ohio State Route 690 now intersects with US Route 50. There still is an historic house at that location, at the intersection of McAfee Road with the connector road to US-50 at County Road 24A. The community now called Canaanville was then called Detroit. Both communities were originally on the railroad: at first, the Marietta and Cincinnati Railroad, which was later the B&O Railroad. Today, that line has been long since abandoned and obliterated.
