I am seeking records of the guardianship of Archie White around 1943 in Oklahoma City, Oklahoma. What court do I start looking or are these transcripts not available? He was about 12 years old. His mother died and his biological father didn’t want him. He stayed with an Aunt until his step-father hired an attorney and petitioned the court for custody. My Dad is about to turn 90 and he has asked me to see if this is available.
