Tom,
I know a little bit about your Ham family's origins before they were in Pendleton District, SC. They actually came from Randolph County, NC, which is why Joshua Ham was able to "witness" the Battle of Guilford Courthouse. It is likely that Joshua's father was named Nehemiah Ham. Nehemiah accompanied him to Pendleton District and was quite a bit older. Also coming with them were some Williams family members on Mary's side. I connect through the Williams. There was Isaac Williams and Edward Williams, in particular. I actually have Joshua's name on one document here in Randolph County, NC -- a road assignment. But he left when he was quite young. This came to mind today because I actually found an atDNA match for my father descended from Joshua's son James. The link, however, is probably through Mary Williams. I descend from a Williams family in the very same area of the county and all of them are proven connected by yDNA. Write to me if you want to know more. Civilisation75@yahoo.com.
