adoptee/47 years old/born in Ft. Worth.might have an older sister

Hi, I decided to start a new thread. Im gonna keep doing a new 1 every so often untill it works. I was told by my adoptive mother and on my real birth certificate not my amended one there was 1 child born before me to this mother that was alive at my birth and 1 child that died before I was born to this mother. My mothers name is on my natural BC as Ruth Ann Cook. But, who knows? I was also told that adoptions that involved lawyers were deceptive. That they sometimes lied about what was the truth on your real birth certificate. Such as birth dates and mothers names. So as of late I post myself as 47 years old born in Texas. Hope you know my mom or sister!!! ceacea
