The Waverly Plantation, outside of Columbus, Mississippi, on the Tombigbee River, was said to have upwards of 900 slaves. However, where archaeology was done, working in the archaeology nearby (William H. Adams et al) it was in the ferry town or village where the large federal project was to create the "Tennessee-Tombigbee Barge Canal" the Tennessee River it's feeder in NE Mississippi and connecting with the canals in Alabama using the Tombigbee River and connecting through Mobile, Alabama with the Gulf of Mexico. Those properties where slaves were, were apparently not very near the Waverly mansion, restored and preserved by historians, but said in another location. Ice from Boston was once shipped up the Tombigbee to the Waverly plantation.
A similar "toponym" had been used in the north, on Long Island they were called "manors" the Gardiner Island Manor, on Gardiners Island, the Sylvestor Manor on Shelter Island investigated archaeologically, the William Floyd Manor the "fourth signer" of the Declaration of Independence and perhaps the first New Yorker to, now part of the Fire Island National Seashore, the Manor of St. George, etc.(?), all had different economies that are still not very well understood from the British colonial era but apparently involved a trade across long sea distances.
