Hi, yes I to used to work for the welfare dept. also.
Have you tried the circuit court? Check with that office first, then yes, check with a "friend" of the court.
I am pretty sure you should find what you are looking for in the circuit court. Let me know how it goes, I am beating the doors of our county circuit court myself, for records back to 1920.
