These sketches are guides to a history of churches within the Indian-Kentuck region, but are not intended as detailed church histories. Churches which are not in the Indian-Kentuck drainage basin, but which are close, are listed here if they drew members from Indian-Kentuck or if they proved important to the development of churches in the basin. These sketches concentrate on the founding date, first records of land ownership, early trustees, and lists of founding members. The dissolution date of extinct churches is given where possible. Churches listed are physically within the Indian-Kentuck drainage basin or close enough to draw members from the region. This list does not include any congregations that were founded after 1900.

Secondary sources used extensively include the History of Milton Township and History of Shelby Township. The date and author are unknown, but both were probably written by William E. Ryker, the president of the Jefferson County Historical Society, and were probably written between 1908 and 1920. Another major source is the History of Switzerland Co., a reissue of the History of Dearborn, Ohio and Switzerland County, Weakley Harraman & Co., Chicago. 1885.

There are official depositories for various denominations, but that doesn't mean the depositories actually have original minutes. Most active churches still have their own minutes if they exist. These depositories are Franklin College (Baptist); Hanover College (Presbyterian); Depauw University (United Methodist). Catholic records are in the Notre Dame University archives. Hanover has microfilms of many church session books, but that's apparently not the case with the other Protestant denominations. Depauw has some church histories (sent by the churches themselves) and denomination records, but no records for many extinct Methodist Churches. Among the most useful Nineteenth Century records at Franklin College are the annual minutes of the state's Baptist Associations. These are useful in determining formation and extinction dates and they give names of messengers and sometimes ministers. A number of church minute books have been microfilmed and are available at the Madison-Jefferson Co. Public Library.

Other records used extensively are the official reports of churches in electing trustees. From the formation of Jefferson Co. in 1811, these are usually recorded in Deed Books. In the 1840s, the record keeping shifted to Mortgage Books. From the 1870s on, they were recorded in Miscellaneous Record books. These are all in the Recorder's office. They can be difficult to find. Sometimes, a trustee election will be indexed under “C” for “Church, Baptist,” sometimes under “B” for Baptist” and sometimes under “T” for trustees.
