I need an Angel in NC; Charlotte or Greensboro

looking for baby boy born approx. 1968-1970...birth mother name is Brenda Bryant...she would have been approx. 23-25 years old. Already had one daughter, 5 years old (me). The birth mother had two younger sisters. She had brown hair, brown eyes. The birth father is unknown by me but I do know he had one young son, blonde hair. Birth certificate is held (we believe) in the Guilford County courthouse in Greensboro NC as that is where the adoption took place. The mother stayed in the Florence Crittendon home in Charlotte NC to have the baby. She lived in Winston-Salem NC (still does).
