Hi I wish I had a definite answer; but, unfortunately, I don't. However, my Looney line was also in Marion County. Mary Looney, oldest daughter of Margaret (Hilliard) and John Looney b. 1793--this date would make it seem possible that your Hettie is a sibling of my John. Mary married Jesse Carlton. Their son, Joshua, married Martha Hooper of Bradley County. I don't have any other information. Much of what I have came from Euline Harris of the Marion County Genealogical Society. She's great. She also sent me some pages from one of their historical publications and I believe that your folks....at least Peter you mentioned is in it.....complete with a photo. Good Luck. CJ Giarratano
