Church and Religious Records

Church records and the information they provide vary greatly depending on the denomination and the record keeper. They may contain information about members of the congregation, such as age; date of baptism, christening, or birth; marriage information and maiden names; and death date. Records may include names of other relatives who were witnesses or members of the congregation. The members of some churches were predominantly of one nationality or ethnic group.

In the decades following statehood, the largest religious groups in Illinois were the Methodist, Episcopal, Baptist, and Presbyterian churches. These groups came primarily from the southern states. At the same time, Congregationalists, Lutherans, and members of the Reformed faiths came from the eastern states. Roman Catholics became numerous in Illinois after 1860, especially in the northern industrial areas. Several counties in the northeastern part of the state became havens for Lutheran Scandinavians.

In the spring of 1839 a group of five thousand Latter-day Saints, following their expulsion from Ohio and Missouri, were led into Illinois by Joseph Smith. At Nauvoo, originally called Venus and Commerce, they established their Mormon community. The population increased, prosperity increased, and opposition against the Mormons increased. This opposition and dissension within their church ended in the murder of Joseph Smith. In September of 1845 the Mormons were told they were being expelled from the state, an expulsion that led to their migration west.

The Bishop Hill colony of Henry County was founded by a group of Swedish immigrants. Fifteen hundred of them, led by Eric Jaanson, established a communal existence of a "Bible only" sect in 1846. The murder of Janson in 1853 led to the 1860 dissolution of this religious community. Most of the Jansonists eventually became Methodists.

The Illinois State Archives collected some early Illinois church records that were given to the Illinois State Library. The Family History Library has microfilms of records from Presbyterian, Methodist, and Baptist churches and copies of many Catholic records from the Chicago area. The library also has some published histories of various denominations, including the Catholic, Methodist, Disciples of Christ, Brethren, Mennonite, and Baptist churches.
