Question: By what name was Key Marco formerly known?
Answer: Horr’s Island
Key Marco is sandwiched between Barfield Bay and Bluehill Bay. The island, which totals 546 acres, was once a pineapple plantation and before that was the home of Captain John Foley Horr. Early native American Indians lived on the island more than 4,000 years ago. Horr’s Island was the largest known community in the Southeastern United States to have been permanently occupied during the Archaic period, about 8,000 years BC.
