I have made a new Family Group Sheet form. This new form is web based and should work fine. Please see the Submit Your Family Information page for information and the link. This is my preferred method of receiving family information updates.
Please check this site to see if you have unclaimed property in the Illinois State Treasurer's office. I know a few of the Weidner's in here are deceased so the surviving family members might be able to file a claim. Good luck.
If you need documents from the Illinois State Archives please contact Molly Kennedy. I have used her services many times since 2006. She is dependable, reliable, and fast turnaround!
