Do you have census records for her? Cemetery records and funeral home records (if they're available) might give you some additional information, also.
Newspapers can be an interesting source. I searched for her in Newspapers and GenealogyBank. I didn't find anything searching for 'Talitha Smith' or 'Talitha Creel', but I found a couple of things for 'Siddie Smith'. Is this the right person?
