I have my mother's Baptismal Certificate from St. Vincent DePaul Chapel, 721 N. LaSalle St. Chicago, IL. Her birth name was Loraine O'Brien. Her parents were listed as Bernice and Grant O'Brien but I don't know if those were there true names. The sponsors were listed as James Mayer and Gladys Boyle. (The penmanship is beautiful but a bit of a challenge to read)
She said she had been told that her birth parents were teachers and could no longer take care of her. She said she was adopted when she was around 9 months old. The earliest photo we have of her was when she was 9 months old.
Posting this hoping someone may recognize the names or might have a suggestion as to how to track down any birth family members. I have searched periodically over the past few years through Ancestry but with no luck.
