I am only about a year too late, responding. Sorry. I never got your query.
I went back to look at what I'd posted, and didn't see that it made any sense, and also didn't see any Nathan... perhaps it was a post even further back than the one you responded to... don't know.
Anyway, the only Nathan associated somewhat closely is that of Benjamin's father, Lewis Wiliams who married Ann Mary Norman. His name was Nathan Brice.I don't have any other information on him, so you'd have to research it to be sure I am correct in stating this. His father was living in Onslow co., NC so you might start there.
Nathan's siblings would have been: Benjamin who married Sarah Battle, Bryan, Bonita or Bonetta, Serena and James. Two siblings married into the Lott Battle family, another sister married Hix.
Afraid that's all I have. If you know any references for Sarah Battle or her husband Benjamin Wililams, I'd appreciate it.
THANKs and so sorry it was so long to respond to your query on Genforum.
