I have found some great information in the Illinois Statewide Marriage Index 1763-1900. A question did everyone have to have a license? I found all of my grandparent’s brothers and sisters, but not my grandparents. Also, how do go about finding marriage information after the 1900. I know the Church was burnt down with records and I believe the courthouse in Joliet also had a fire. Thanks for your help! Marjory Kennedy
