I will visit the Will County Clerk’s Office, and search the birth certificate index for the requested individual. The index roughly includes the years 1877 through 1937. This index also includes any delayed birth certificates that may have been filed at a later date. If an entry is found in the index a certified copy of the birth certificate can obtained the same day. Certified copies of the birth certificates are $9.00 a piece.
Indexes are organized by beginning letter of the last name. Outside of that the organization of the index varies. Additionally it is a combination of handwritten and typed entries. It requires each page of the index to be searched. Generally I can search one index in 45 minutes to an hour.
