Whew! That took me a while! There's nearly 50 pages of Hardison and over 20 pages of Stewart names!
Okay, I did not find ANY of these people you are looking for. There were, however, names like Elizabeth A. Stewart (but with dif. husband), Thomas P. Hardison with a Mary A. Hardison, and a few other off-names like that. But none of yours. You know, there are actually 8 cemeteries in Maury Co., TN named Hardison Cemetery? Sorry I couldn't find who you were looking for. I looked for all the names you have mentioned too.
