looking for my parents

hi, i was born in vietnam in 1970 OR 1971,i think in july. i believe i was born at the big children's hospital in saigon,im not too sure. i don't know my parents' names or anything. so i don't know who my family is. i was never adpoted ,i lived with a vietnamese family for many years. they are,understandably unwilling to ever give me info. or acknowledge my true identity. its just not talked about. i know my father is american and my mother is vietnamese. and the name they gave me when i was at the hospital was "Hanh Dung Doan Le". the lady who worked at the hospital, the nurse,her name was Minh. She took me to the home she was living at. i do know her but can't ask info. of her.did anyone work at that hospitalat that time and remeber me?I was in a "glass" thing for awhile,they said i had trouble breathing.i realize my info. is so vague,i'll probably never find my parents. but nothing isn't worth trying.i'd like to know my family,cousins,etc.that would be so cool.so u know of any dna match ?or peopel i can talk to and meet who share the same situation?dad,whoever u are,you'd be very proud of me,i am a good ,independent person, who just wants even to have your picture and know what u look like,and what my grandma and grampa look like and if i have siblings,or if i got my goofy sense of humor and extreme work ethics,from you.
