ISO F Born in TX in 1980 around Houston, possibly around Corpus Christi

I'm looking for my half-sister born in Texas in 1980. I realize that is not a lot of information, but I do have information about your birth mother, and judging by the pics of her, me, my sister, and my other half-sister, you likely resemble one of us. I was born in 1982 and my sisters after that. You were put up for adoption right away; our birth mother held you maybe minutes and that was it. I was born in Houston so you may have as well, but she had family in Corpus Christi at the time so you may been born there.***Edited: I should add that we are Hispanic, but both my sister and my half-sister are very fair-skinned so you may be too. My half-sister looks more Hispanic than my sister does though. Our birth mother is Mexican. We don't share the same father as you so I know nothing about him.
