Amanda Jane Creech (Flannery) - Amanda Jane Creech Flannery's birth mother

Does anyone have any information on the birth mother of Amanda Creech? Is Bluford Flannery her biological father or was she adopted? Amanda is my 2nd great grandmother (Sudie Creech my great grandma). I'm very curious to know who Amanda's mother is and why she was not together with Bluford.

Thank you for any information.
