texas search angel

First of all, give yourself a pat on the back for helping others with searching. It is very kind and giving of you. I know I would appreciate any help or pointers you could give me. I was born in san benito, tx at Dolly Vinsent Hospital. My birth certificate states NONE of that but I was able to verify that through txvitals, and dolly vinsent was the only hospital open there at that time. My birth certificate states Precinct 2 with no hospital listed, & I still don't know what that means. My birthdate is 1-18-1971 at 3:33 pm, and I was adopted at birth. That is pretty much all I have to go on. Can you help me find a direction to go in? thank you for your time, & good luck to you in your own search.
