Sorry for delay in responding - computer problems. After my posting I received info contridicting what I originally had been provided. It seems to match yours as it indicates Andrew not Thomas as a doctor. It also says Andrew Fullwood was adopted in SC by a Thomas Fullwood for whom he apparently named a son (the father of your Anna I think).
I've been told that Anna was born in 1804 in Onslow County, NC and that she married William P. Dennison who was Captain of the Ware County militia and a justice of the Peace after they moved to Ware County. The site of the home became in due course, Clinch, Lanier, and Echols County as new counties were formed. They had six children.
I haven't confirmed any of this with research. I just archive EVERYTHING I find on Fullwoods for possible future use and research it only when I am able to connect the person to my ancestors.
