I've been looking for info on Pete Marable who married my Great Aunt Lucille Key. I know they were from the Jordan Springs, Tn. area (part of Woodlawn Tn). I googled "Jordan Springs, Tn" and it pulled up a web site that listed several Marable's. http://www.tngennet.org/montgomery/obit-3.html
Pete and Lucille had a son named Lacy Gilmer Marable that died as a child. His obit was one of the Marable's listed on this site. There is a lot of info on the Marables that may help link your Marables to them. I'm still looking for Pete's parents or siblings if anyone has that info.
