I would follow the same formatting as done for Bahamas. Even though it is not Caribbean. I thought it should go under a North American but that has not been the habit. Please see link. I also added a link for the how to format page

But I will note that I’ve seen some cemeteries in Cayman Islands and they are not under Caribbean. Now I can’t find them so I cannot tell where they got inputted.
