Exactly! As much as we could go to fanfiction, we mainly strive towards accuracy, which is mostly found in Disney-confirmed material. Hopefully, a name for the island would be revealed in the official POTC site...like it did for some of our other articles, like confirming Cuba as Tia's home and the official names of many objects, places and organizations(including Black Sand Beach and Pirate Armada).

Oh, and welcome to POTC Wiki Kakoolookiyam! :)
