One of the finest historical Web Sites on the Internet is the Library of Congress - American Memories Web Site. One of their collections is Railroad Maps. It covers many regions and many time periods. The 1854 County Map below was cut out of one of its Illinois Railroad Maps. It takes time and patience and lots of memory to download one of their maps so we may not do many but it is a fun site to visit.

A map of Mercer County was published and sold in 1856 but we have been unable to locate a copy. According to the Illinois Regional Archives Depository the earliest map of Mercer County in existence is from 1864 and is currently located at the Mercer-Carnegie Library in Aledo. Maps at the Essley-Noble Museum include: 1864 by Thompson; 1875 by Brink; 1892 Plat Book; 1904 Hixson; 1923 Plat Book & Farm Ownership.

The Mercer County Historical Society has an old undated map on their web site that shows locations of the old towns as well as township lines.

The U. S. Geological Survey Maps are up on the Internet. Places can be located by town, township, or feature name. U. S. Geological Survey topographical maps are also on line. On the topographical maps your spelling of a feature must be exact. If it doesn't have what you want try alternate spellings. The easiest way to use it for Mercer County is to ask for New Boston in Illinois. When that comes up there are clickable arrows on the side of the map to move north south east and west from New Boston.
