Searching for birth mother's family Barbara Ann Wood - born NY, I believe 1940's

Hi there, I'm just searching for relatives who may know more information about my birth mother, Barbara Ann Wood. She was married to my biological father James Howard Sexton of AL during the 1970's, and moved from Chicago IL to Avon Park FL with him where I was born in 1978. She herself was adopted I from a NY orphanage I was told, and may have been married to a Kenneth Cook of FL at some point as well. Thank you so much!
