Mother was adopted, born 2/20/59

I am the child of an adoptee who was born on February 20th, 1959 according to her records. I'm not sure if this is her birth name, but her first and middle names are Jacqueline and Rose. She was adopted by a family who lived in south Palm Beach County, Florida. She has blue (very slightly green) eyes, fine complexion, and was born with blonde hair but turned medium brown when she matured. She has naturally thin, light-colored eyebrows and is about 5'7"-5'8". My mother is the kindest, sweetest, most giving, warm-hearted woman. Thank you for your time.
