Here is the birth certificate for my grandmother, Louise Mary Daniels, born April 19, 1914 to Mabel (Cass) and Fred Daniels in Chicago, Illinois.
The family was living at 4647 Winthrop Avenue, a block south of where they would eventually build the Daniels Apartment Hotel.
Cook County, Illinois also had a birth register. Louise is listed as number 4024 on page 1 of the register, along with the birth location and age of the father and mother.
Page 2 of the register lists the mother's maiden name, the father's name and profession. The last column is the name of the doctor.
