ISO Sister born 1-24-72 in St. Louis, MO

I am in search of my half sister that was given up for adoption by my mother. She was born on 1-24-72 at what is now St. Louis University Hospital, it use to be called Firmin-Desloge Hospital. The only thing I know about my sister is that she went to nursing school. Your birth mom's name was Joyce Carron. She gave you up so you could have a better life. She was young. Please respond or anyone that may know who I am talking about. Thank you.
