searching for sister 3/1967

I am searching for my sister. She was born 4 years before me in march of 1967. my mom was 14 at the time of her birth.My moms maiden name was Gschwind. my sister was born in Asheville,NC but was taken back to TN where my mom lived and placed for adoption through TN DCS. I have her birth name but not her adopted name and I have a description of what she looked like as a baby. PLEASE if you think you might be her or may know how to find her,let me know!! I've sent a letter to the ppost adoption unit in Nashville requesting info...but you know how that goes!! I can be contacted at dwsn3a@aol.com. I just want to find my sister so badly.
