The land is on the banks of the Cape Fear River and was partially a grant from King George III for Col. Richardson's gallant service with General James Wolfe in the French and Indian War.
The Colonel became interested in the land after he and his brother were shipwrecked off of Cape Hatteras and had to spend several months making repairs in Bladen County, NC before they could return to their home in Stonington, Connecticut.
[1] In a local legend associated with the home, General Cornwallis used Harmony Hall as his headquarters for a time during his march to Wilmington, North Carolina.
However, careful historical analysis has shown that although General Cornwallis marched within several miles of Harmony Hall, he was always on the opposite side of the Cape Fear River.
The legend may have some truth, as there is a chance that the Richardson ladies relocated during the war and had contact with General Cornwallis at some different location, but there is no way to determine this.
