It is possible that whoever did her obit, did not know her maiden name, and did know the Ward name of her daughter. It happens a lot on death certs. You should try to contact the person who owns the Inman website. They may have more info. I am not related.
I looked at the cemeteries that are listed online, but had no luck at finding where she is buried. You might try contacting the Genealogy Society there, to see if they have a list of the cemeteries, or an obit listing the cemetery. You will find that there is very little that is listed online.
