Siblng looking after Bio Parents have both deceased!

I am the sibling of a baby boy that was born or adopted on Oct.28th, 1978. The birth mother was doing time in a Florida prison. The bio mother and father are both deceased now, and I am looking for this lost loved one! This mother may have had an alias name due to serious drug charges and her safety may have been an issue. Her "real" last name was Goldner and she would have been around 22 years old. This person is caucasian and may have a dark olive complexion. Any caucasian males born or adopted around this date in Florida, please contact me. Jusme1304@aol.com
