Girl looking for BirthparentsDOB 3/10/78

I am looking for my birthparents. I was born March 10, 1978 in Louisville KY. I was adopted through Catholic Charities. The only information that I have is that my father was part Sioux/ Cherokee Indian and that my mother was about 5'3" with brown hair. She was 17 and my father was 18 when I was born. Any information would be appreciated.
