Hi, I got copies for . 50 each from Warren County Clerk, but I understand fees do vary. Warren County did not show parents but the copies are great to have and look at, if nothing else. The following info might help. County clerks are the official custodians of all marriage records recorded in Illinois counties. To obtain copies of marriages found in the Illinois Statewide Marriage Index, you may write the appropriate County clerk including in your letter all of the information on the marriage given in the Marriage Index. Search and copy fees will vary from one county to another. Knox County Courthouse Galesburg, Illinois 61401 Good luck!
