Hi..You sure that this Susan wasn't a Susanna????? My ggrandfather Thomas Nicholson was married to a Susannah..and it is listed that she is from S. C. They had lots of children...He is listed as 34 and she 24 in 1850 gilmer co, ga census; by the time he died, he remarried and had two more children...We were from Dalton, Whitfield, Ga...but some of their kids lived in Marietta...Ga..If you think this is the person you are looking for...I may be able to help you..
