I am researching ancestors who lived in Flat Rock, DeKalb County, Georgia, at the time of the 1860 and 1870 censuses. First, I am seeking a better idea of exactly where Flat Rock was. I know it's somewhere in the vicinity of Highway 155 and South River, but from other descriptions I've found, I'm assuming it was larger than what I originally thought. And, I'm not sure if it was on the east or west side, or both, of Highway 155. Also, I am seeking information about a grave in Master's Cemetery. I have Franklin Garrett's 1931 readings of it, but after visiting the cemetery some years ago, I realize he did not have an ancestor, Lucy Primrose, on the list, although I saw her above-ground grave when I was there and took pictures of it. What I did not take a close-up picture of was the above-ground grave next to Lucy's. I am trying to determine who was buried there, and I assume it was one of her three husbands, because of the arrangement of the two "boxes." If anyone has suggestions on helping me with these two questions, I would appreciate hearing from you. Thanks. Coleen
