Ron, I'm sorry, I intended to get in touch with you on the Downs information that I have. If you don't mind, I need to clarify some of the information you posted.
Thomas Matthew Downs (Find A Grave Memorial# 39541931) is buried in Mitchell Cemetery, in Rogersville, AL, but his daughter, Lillian Mae Downs Griggs (Find A Grave Memorial# 16450788) is buried in Legg Cemetery.
Margret Roberts Downs (Find A Grave Memorial# 14445781) d: 13 Jun 1888, and is buried in Roberts Cemetery in Giles Co., TN.
I do not have any information on the children of Thomas Matthew Downs and Eliza Coffman, other than their names and birth/death dates, if that much.
I hope this will help with your research. If you have any questions, please feel free to contact me at email@example.com
