The Mattabeseck Indians called these small outcroppings “Kuttomquosh,” meaning “beautiful sea rocks.” These days, they are called the Thimble Islands. Some of them are so tiny that debate goes on over whether they are actually islands or just rocks. Depending on which camp you are in, you can count from 100 to 365 of these land masses clustered just off Branford, Conn., in the Long Island Sound. In 1614, Adrian Block became the first European to set sights on the Thimbles, but they didn't remain uninhabited for long. Stories of treasure buried nearby by Captain Kidd brought hopefuls in search of gold. The treasure was never found, but today the tiny islands have become a treasure trove of real estate. There are 81 summer homes in all; the smallest islands hold one or two, and the largest island, Money Island, has a village of 32 homes and a post office. The houses are built in a variety of styles and sizes. One island boasts a 27-room Tudor residence with tennis and basketball courts, others have small summer cottages on stilts or clusters of buildings connected by footbridges. The lure of the Thimbles has changed with the times. Once, they enticed those looking to get rich, while today they attract those who are already wealthy.
