In the Lighthouse, we see various names. Among these names were Rousseau, Faraday, Lewis, Dorrit, and many 815 passengers. All of them came to the island, and the ones who died were crossed out. Haasra and Grimwault are names we haven't been introcued to yet, but they haven't been crossed out yet. So either they have come to the island previously, or they will come to the island later on, and they will be of high prominence.
