I am also interested in also info on Nimrod or Dawson. Just yesterday I found Dawson listed in the Edgefield Advertizer on 9/30/1875 and it said that Dawson died on 9/15/1875. I can email a copy if you want it. I come off of Dawson's daughter Frances who married William Tiller. I have been trying to find any info on this William Tiller. I found Frances in the 1883 Augusta City Directory and it comfirms she was a widow of Willam Tiller.

Thanks,
Christina
