I have 2 of the 4 obits you're looking for: Nettie Richards and Gladys Tolbert. Please contact me (firstname.lastname@example.org
) and I will email you the copies.
The Chattanoooga Library has an obit for an Albert "J" Rankin dated 9/12/1957 and one for Mrs. Nellie Jane McClendon for Jan 1993. These might be the ones you need. When you contact me via email, I can give you instructions on how to get that information.
