Rejenia, I don't know if this will help or not. My mother was born in 1904 near Jeffs in the Chickasaw Nation. She got a delayed birth certificate later, and one of the proofs that was legally acceptable was the school enumeration. >From the Guide to the Historical Records of Oklahoma by Bradford Koplowitz--under Nowata County, p99: "Superintendent of Schools School Enumeration. Name of parent, name of child, date of birth, age and grade, alphabetical , 1912-1919." I have never researched these records, but I believe they are in the county courthouses. The County Superintendent of Schools no longer exists in most counties. It might be you would need a researcher to find these records. The address for the courthouse is: Nowata County Courthouse 229 N. Maple St., Nowata, OK 74048 (918)273-0175
