I do not know if this will help you sort out the Elliotts of Forsyth Co Ga., but this is factual data from my files. Please use it as you see fit: James Jackson Elliott (1816- 1888) married Matilda Freeman in Habersham Co Ga. They are in the 1850 census there. By 1860, they are living near Crossroads in Forsyth Co. Ga. They have several children that I have in my files.
Two of their children married my great uncle and aunt. Rose Etta (1857-1895) married Amaziah Jamiah Smith(1854-1938). They had Martha L., Barney Eber, Hampton C., and Mollie. Rose Etta died at the birth of Mollie.
Barney F. (1860-1894) married Coloma Sarah Smith . They had only one child Claud E. Elliott. All the above are buried at Shiloah Methodist Church in Cherokee Co Ga.
Amaziah and Coloma were the children of my gg grandparents: Thomas Harrison and Harriet Elizabeth Smith of Yellow Creek Dawson Co. They were from South Carolina. Living next door to Amaziah and Rose Etta in Forsyth Co Ga were my great grandparents: (older brother to Amaziah,) William Joseph Smith and Mary Gilstrap Smith. Mary was the daughter of Charles Asberry Gilstrap and granddaughter of William M. Gilstrap and Delilah Durham from Pickens Co SC to Forsyth Co Ga before 1860.
I have detailed information about the families if you are connected and want it.
