A searchable index to Illinois marriages occurring prior to 1901 with the names of the groom and bride, the date of the marriage or issuance of the license, the name of the county in which the marriage was performed, and a citation to the original record. Data entry has been done by Archives staff and volunteers. "Although the primary aim of the project is to enter marriages occurring prior to 1901, some volunteers have chosen to enter a county's marriages through 1920."
