Jackie Kennedy Onassis' estate on Martha’s Vineyard is up for sale. Her daughter, Caroline Kennedy, is putting it on the market for $65 million. “Martha's Vineyard will always be a part of our lives. But it's time for us to follow my mother's example and create our own world. We hope that another family will treasure this place as we have,” Caroline says. Caroline's decision to sell the estate, known as Red Gate Farm, comes just weeks before the 20th anniversary of her brother JFK Jr.’s death.
