Histories are great sources of genealogical information. Many contain biographical information about individuals who lived in the area, including:
Some of the most valuable sources for family history research are local histories. Published histories of towns, counties, and states usually contain accounts of families. They describe the settlement of the area and the founding of churches, schools, and businesses. You can also find lists of pioneers, soldiers, and civil officials. Even if your ancestor is not listed, information on other relatives may be included that will provide important clues for locating your ancestor. A local history may also suggest other records to search. Local histories are extensively collected by the Family History Library, public and university libraries, and state and local historical societies.
County History Indexes by the Work Projects Administration
During the late 1930s, the Work Projects Administration (WPA) carried out a program of indexing county histories, atlases, gazetteers, and miscellaneous records on a county-by-county basis. These were given the title Index of Names of Persons and Firms. The Family History Library has these indexes in book form or on microfilm for most counties. They are listed under:
- INDIANA, [COUNTY]- BIOGRAPHY- INDEXES
- INDIANA, [COUNTY]- HISTORY- INDEXES
State Histories Useful to Genealogists
Good genealogists strive to understand the life and times of their ancestors. In this sense, any history is useful. But certain kinds of state, county, and local histories, especially older histories published between 1845 and 1945, often include biographical sketches of prominent individuals. The sketches usually tend toward the lauditory, but may include some genealogical details. If these histories are indexed or alphabetical, check for an ancestor's name. Some examples for the State of Indiana are:
- A History of Indiana from Its Exploration to 1922.  Each volume is indexed and contains information on the early development of Indiana. Volume three is a history of St. Joseph County.
- A History of Indiana: From Its Earliest Exploration by Europeans to the Close of the Territorial Government, in 1816. 
For Indiana records concerning the years 1787 to 1816, see:
- The Territorial Papers of the United States  Volumes two and three are on film  and contain information about persons who resided in the area that now includes Indiana from 1787 to 1803. Each volume contains a name and subject index.
- The Territorial Papers of the United States volumes seven and eight  contain The Territory of Indiana, for 1800 to 1810, and 1810 to 1816. Each volume has an every-name index and contains thousands of names of residents in what is now Indiana. There are lists of residents of particular counties who signed petitions to the government between 1805 and 1816, and information about persons associated with forts, land offices, Indian interpreters, express riders, and post offices.
Additional Sources For Historical Information
Much historical information about early settlers in Indiana is found in the following collection:
The Draper Manuscript Collection
The Draper Manuscript Collection is a significant regional source that includes records of Illinois.
- Draper Manuscript Collection The collection consists of nearly 500 volumes of manuscripts, papers, and books collected by Lyman Copeland Draper about the history of the trans-Allegheny West, a region including the western areas of the Carolinas and Virginia, all the Ohio River Valley, and part of the upper Mississippi Valley from the 1740s to 1830. The collection is divided into 50 series. Some series are titled by geographic area, some by the names of prominent frontier leaders, and some by topic. The bulk of the collection consists of notes from interviews, questionnaires, and letters gathered during Draper’s extensive travels and research to learn about frontier history. Personal papers are much more rare than government or military records.
The collection includes many items of a genealogical or biographical nature. For an inventory and partial indexes, see:
- Guide to the Draper Manuscripts  This guide gives series and volume descriptions for some of the Draper manuscripts. There are several indexes at the end of the book, including a name and subject index, an additional personal data index, and a list of references to Illinois.
- Index to Lyman C. Draper Manuscripts.  The name index gives the series and volume numbers, but is not complete.
