ISO Birthmother- I was born 9/30/72

My name is Amanda and I was born on 9/30/72 at St. Francis Hospital in Greenville SC. I'm looking for my birthmother who was in her teens at the time. I don't know if she lives in Greenville or who she is but I want her to know that I think of her always. I also don't know much beyond her age so it's been difficult even finding a place to start. It was a private adoption through Jack and Lillan Bloom. Any help would be greatly appreciated. You can also contact me at (718)275-4461. Thanks
