This is a "Wild Mass Guess" entry, where we pull out all the sanity stops on theorizing. The regular entry on this topic is elsewhere. Please see this programme note.
The Green-Eyed Elf is Galadriel (imposing queen), Lorengorm is Elrond (his sideburns look like the ones he has in the movie), and the Leaf-Horned Elf is Círdan the Shipwright (only one with a beard). After Middle-Earth had become Europe, The Grey Havens presumably had become America.
