seeking birth family

Hi. I was born in Memphis, TN Feb 18, 1971 the adoption was processed by mid-march ֖ I dont necessarily want full blown contact with my birth family Җ Im very happy and well adjusted with my adoptive family Җ Im mostly interested in family trees and medical history. Not a lot is known about my adoption Җ I called Nashville and felt like I was being stonewalled I am mostly interested in this for my wife and newborn daughter օ I still live in Memphis and am very happy/ well adjusted, etc I just donŒt know where to start with this as Ive no patience for red tape҅ Blake
