Before contacting the UGA contact the FOrt King George in Darien Ga also Fort Frederica on Saint Simons Island Ga 15 min south of darien as this was the fort in which Gen Oglethorpe built and whom the Highlanders where fighting for. They were known as Oglethorpe's Highland Independent Company. I lived on St Simons upo until June, and was part of Clan Nan Con, a reenactment group portraying Oglethorpe's Highlanders. It is to note to that the tartan worn by these scots were of a non discript tartan and they all looked very much like typical highlanders of the time. The only thing uniform were the blue bonnets and the black cockade denoting crown service.
Cheers,
