Hi again - that helps, but I'll confess that I'm a little confused. You are trying to find your father's (Robert's) biological father? Robert's biological mother was Carrie - what was her maiden name and married name? Date of birth? Have you located your father's birth certificate - does it give his parents' names? You knew Carrie personally, or know her descendants - do they offer clues? Do you think Carrie or her child's biological father may be related to Joseph Jess Jones or his wife Mary Estelle (foster parents to Robert)? I'll go ahead and list some records for Joseph Jess Jones, and check back with you.

I did not find a Garnett Jones in Oklahoma who could be your father's sister. Was her surname Jones? What year was she born? The following census is NOT Garnett, unless the census taker erred in noting the gender. You said Garnett was raised by Mary Estelle's sister Edna (no maiden or married surname given).
