- Elaine Gamble grew-up at Castle Hill. Her father, Dave Gamble, was the plantation's superintendent for 20 years. Elaine shared the following with us: "Castle Hill's nine-tenths of a mile entry lane is lined with bunkers on either side from the Civil War. Several cannonballs were found on the property as well as medical bottles.
"The plantation has a rather large pond, possibly up to 100 acres including wetlands, which is populated with alligators. There is an old rice field that was used for duck hunting and a slave cemetery next to the pond complete with very old headstones [from the] late 1800s.
"When I grew up, it had a prize-winning camellia garden which my father and Dr. Wearn cultivated and won many blue ribbons with. Castle Hill Plantation was visited by many well-known figures including Henry Cabot Lodge and E.B. White."
