looking for my birthmother. Bogota Colombia, South America

Greetings, My name is John. I was born John Edwin (or Eduardo) Rodriguez on Sept. 28, 1979. My mother is Helena Rosa Rodriguez-Clavijo. I have never met her. I was adopted at age 2 by a wonderful American family. But, I am looking for my birth mother. I was born in the hospital San Juan de Dios in Socorro, Colombia. I was adopted from an orphanage in San Gil (Sand Hill), Colombia. My goal is to meet my mother and find out who I am. Good luck to those who are also trying to meet their parents. If anyone knows how I can find mine, please let me know. Sincerely, John
