The names you quote are for the water parts (bays of the Dutch side) and don't necessarily pertain to the landed neighborhoods. Names evolve over years and the original names get lost. In order to get a local skippers license, you have to know the names of all the bays ( water areas) on the Dutch side to pass the test. The bay where Indigo Bay development is still called Cay Bay. Indigo is just the name of the development and does not change the name of the bay.
