Henry Burr Sherwood owned and operated the Compo Tide Mill inventing a farming implement important for the local onion-growing economy of the Westport/Fairfield area

The Sherwood Mill Pond at Compo Cove is a large tidal pond hugely significant to the settlement and historical development pattern of the local Westport - Compo - Greens Farm area. The tidal flow from Long Island Sound was a significant source of power in the 18th century leading to construction of one of the earliest grist mills in the area (rights granted ca. 1705 by the town of Fairfield CT). The tidal pond also hosted fertile and productive oyster beds. The original grist mill was built by a John Cable; but by 1790 had been acquired and rebuilt by Sherwood family members to service local farmers. Henry's father Daniel, and uncle Ebenezer, improved the mill by erecting a substantial breakwater, wharves, and sluice gates
