Adopted in Ft. Worth - stories of mother from Colorado -1950's

Hi Everyone, I am trying every venue I can regarding my adoption. I already have all the identifying information. I petition the courts in Texas in the 80's and won. BUT! I still cannot find my mother or my other sibling or siblings. I was told a story by my adopted mother's close friend, ( they are both now deceased). It was that the year before I was born my parents had took a trip through Colorado. Another time she told me my birth mother went back to Colorado after my birth. No one in my adopted family ever mentioned either one of those things happening.I did see pictures of Colorado. Of course my adopted family took all my information to their graves with them! So after beating down every bush in Texas, I am now targeting Colorado. Funny, I keep moving back here....... CeaCea
