Bob-yes, Elizabeth Frances Amanda RHAMES was Robert Lawson WHITFIELD's second wife and had 3 children by him. After Robert died she married W N WISHARD on 13 Sep 1882. She died on 24 Mar 1924 and is buried in Pleasant Rest Cemetery, Gulf county, FL.
I had no census data on her and went searching last night. Nothing found in 1850 or 1860. Will do some more searching today.
Elsewhere you mention "Bart Rhames"; I believe this is Jeremiah Benjamin RHAMES, son of Levi J RHAMES and nephew of Elizabeth.
I regret that I can't provide solid sources but if memory serves me correctly, my data came from a RHAMES family member.
