My mother and her sister were adopted many years ago and she has exhausted all avenues of getting a true birth certificate. She is now 72 years old and her mother has passed on also. Her sister (also now passed on) had a birth certificate of her own but my mother has never had one. The adoption was private - she was born in Chicago, IL. If anyone has any information on how to fulfill my Mom's wish of an actual birth certificate, I would appreciate any help. thank you.
