Mollie Chatham

I am trying to find information on my great grandmother’s family. I know she was born in Nashville, TN in 1858. Mollie married Thomas W Roberts. Her father is WIlliam Chatham. I believe her mother’s name is Mary Wood or Woods but have not been able to confirm that. It has been told that there was an uncle John who lived across the Cumberland River from them. He and his wife, Harwella, where married for 45 years. He allegedly died on their anniversary.
Any help that can be given is appreciated!
