Origin
By surface analysis, Morgan + island * (island in South Carolina): Originally named as Morgan's Island, named alongside the bordering Morgan River. Attested without the possessive marker since at least the mid-1890s. * (island in the Indian Ocean): First appears as "Morgan Bay" in 1860, of which this island was a part. Later coined as Morgan Islands, plural, to describe the same region. The name for the island stuck during when being surveyed during the Australian National Antarctic Research Expeditions in 1948.
