Local tradition has it that a "minstrel boat" arrived here when a survey crew was working in the area. That boat was almost certainly HMS Amethyst, which in 1876 took the Governor-General (Lord Dufferin) and his lady on a cruise upcoast to Metlakatla. A member of her crew (Patrick Riley, Memories of a Bluejacket, p.87) mentions that Amethyst had an amateur troupe of 'nigger minstrels' - these entertainers were generally white and made up with black faces - who provided entertainment for their shipmates and, presumably, any visitors, so it seems highly probable that Minstrel Island commemorates a performance in these waters. Nearby are Bones Bay and Sambo Point. Both 'Mr. Bones' and 'Sambo' were stock characters in the minstrel shows that were so popular in the late nineteenth century.
