It was named for King George of England.
"I leave the pleasure to inform Your Lordship that the part of the road to the Musquito, which Governor Grant had contracted for, and to be completed before Christmas next, is just now finishing, and is done in such a manner that it will not require any additional repairs for many years. The Bridges are firm and substantial; the causeways well made, and the road well opened. A Cart of Waggon, or any number of them, may pass with ease on twenty miles of good road toward the Musquito. But this My Lord is not quite half way to the first water Carriage on that river; it being about twenty-five miles from the road where the new Road now terminates...". - Lt. Governor John Moultrie, September 27, 1771
