1883 Gallatin Carroll Atlas
The Historical Atlas of Carroll & Gallatin Counties of Kentucky, originally published by D. J. Laake & Co. in 1883, has not only been re-printed, but fully indexed by William A. Davis. He's selling them. The Atlas contains many plats of all of the towns in Gallatin and Carroll as well as all rural portions of the counties.
You can find out more by dropping him a note at PO Box 337, Ghent, Kentucky 41045. He's also willing to do lookups for you in the index.
