Looking for Korean Birth mother from Augusta Georgia 1974

My name is Jason. I am unsure when exactly I was born or at which hospital. I was given up for adoption sometime in the fall of 1974 in Augusta Georgia and adopted in Macon. My mother was Korean or Korean American, verified through DNA testing. She may have been only 14 or 15(this may or may not be true). I am connected to the Manning family of Augusta also confirmed by DNA (I am not in contact with them as they do not appear interested in communicating). I have narrowed down my birth father to two candidates but I am not interested in knowing much more than who he is. My birth mother may have attended Glenn Hills High School in Augusta during the 1973-74 school year. Thank you for any information you can provide.
