Jim,
The Cincinnati city directories are not available online. You would need to visit the main library. I did check the online Census for 1860 and did not find a RACHING listed. However, the online Census that I use doesn't allow for a Soundex search and the name could have been spelled many differnt ways by the census taker.
Best bet is to locate someone in the Cincy area that can check the city directories. I only get down there every couple months. I'll make a not of this and will check the next time I'm in Cincy.
