Son looking for Birth Mother in Texas

I'm looking for my Birth Mother. I was born in San Antonio TX on Jan. 9th 1966 at the Texas Cradle society. I don't know very much, I do know she had a Brother in the Military at the time. I believe she was 21yrs old, her physical description that I have is short of stature with Blond hair. If anyone has any info, my email is david.lordwhyte@gmail.com
