father

You may want to include her birth date in your subject heading, or at least within the body of your post. Your daughter most likely doesn't know her birth/first mother's name...unless they've already been in contact with each other. You'll be more likely to get a response if you include the city of her birth also. Good luck. I hope your daughter sees your post. Have you signed up with all the online search/reunion registries yet?

she was born in jacksonville fl.

I was born in Jacksonville, FL in 1974. I do not know my birth mother's name. My birthdate is 9/9/1974 unless it was changed to that which was a common thing back then. I do not know what hospital. Do you have any other information?
