ISO birth family, Homestead AFB 1971

I am still looking for any birth family members. I was born at Homestead AFB on 12/28/1971. My birthmom was 20 yrs old and very skinny. She liked to sew. She had worked as a telephone operater I believe. She had moved to a "West" state where she met my birthfather. He was 22, had been married before with one child. He was a railroad engineer. She moved back to the "southern" state she was from to have me and my birth grandparents talked her into adoption. My birth grandfather was a military man who had retired, he was 54 and my birth grandmother was a homemaker, 54 also. My birthmother had 3 or 4 siblings, mostly girls and one boy I think. My birthmother was born somewhere near the Panama Canal. The attorney that handled the adoptions was Carl Lak (I think that's the spelling). If you know anyone this sounds like, please contact me as I've been looking for 10 years with no luck. Thanks!
