Church records may include baptisms, marriages, first communions, confirmations, deaths, interments, membership lists, and other records. Records for auxiliary and social organizations may also be included. However, not all collections include the same information. Researchers are encouraged to consult the finding aids for specific information.

Early records from congregations of German origin may be in German. Early records from Roman Catholic churches may be in Latin. Through an agreement with the diocese of Toledo, there is a seventy 70 year restriction on access to baptism and marriage records. For more information, see Access to Diocese Records.
