Mother-in-Law Island

Money Island is one of the Thimble Islands off Stony Creek, a section of Branford, Connecticut. It is named after a legend that Captain Kidd buried his treasure there. The island, 12 acres (49,000 m2) in size, bears an entire village of 32 houses, a post office, and one library. Former buildings included a school, a church, and a grocery store. There are three roads and several piers. At this time, none of the houses are occupied year-round.The three roads are Montowese Avenue, Pequot Avenue, and Kidd's Lane.

Horse Island, at 17 acres (69,000 m²), is the largest of the Thimble Islands off Stony Creek, a section of Branford, Connecticut. It is owned by Yale University and is maintained as an ecological laboratory by Yale's Peabody Museum of Natural History. It was purchased and donated to the university in 1971 as a convenient addition to the Yale Coastal Field Station in nearby Guilford, which has its own dock and boats, and is also managed by Yale's Peabody Museum of Natural History.A large house on the island has been kept in good repair and can serve as a base for experimenters or others remaining on the island for overnight stays or longer. According to the Yale Alumni Magazine, "Horse Island used to be a summer retreat; there’s still an eight-room house and evidence of a tennis court. The island now functions as a natural classroom, used for research and teaching. It’s also visited by a wide variety of migrating birds, which are actively studied by Yale researchers." In 2020, Yale faculty and students from the School of Architecture partnered with the Peabody Museum to build a teaching and coastal research center for the Yale Peabody Museum of Natural History. The center was built using a "regenerative approach." This approach aims to reduce the carbon footprint of the building, from construction to daily use, and limits the number of toxic materials used during construction. The Center will function off-grid with a kitchenette, toilet (which incinerate waste into ash), and two bunks for sleeping. The Center will feature a 30-foot-by-16-foot classroom with projection screens and barn-style doors.The origins of the island's name are not known. Some say that at some point a cargo of horses may have found its way to the island from a capsized or wrecked ship, but no physical or documentary traces of such an event exist. Others speculate that the island's horseshoe shape may have influenced its name. For many years it was owned by an executive of Standard Oil named Clark, and was called "Clark's Island" by everyone. When James and Esther Rettger purchased the island in 1946 they restored the original name as found on the geodetic survey maps.

Governor Island is one of the Thimble Islands off Stony Creek, a section of Branford, Connecticut. It has 14 residences, although none are inhabited year-round.Inhabited initially as an oyster company's base of operations. Since pigs will feed from an oyster shucker's waste pile, a "watch pig" was installed rather than a dog, eliminating the daily row out to feed the animal. The assertiveness of this pig quickly earned it the name "Governor". By the fourth season, the pig had grown so large and onerous that it kept even the oystermen off the island. Something had to be done since this was a commercial operation. In memory of the first pig roast, the island was named "Governor's". There remains a debate among the older islanders if Governor was a pig or a goat; with recent gentrification looking down upon "goat roasts".One of the oldest houses on the island was built in 1880 by R.H. Brown and is still held by his family's descendants. R.H. Brown was a notable Connecticut brass manufacturer and is known to have made some of the finest yacht cannons ever made.
