Elfwine

'Elf-friend' is also the meaning of the name Elendil, Aragorn's ancient and noble ancestor. In fact, Elfwine's name - in different forms and variations - has a long history in Tolkien's works. In some of his earliest writing (The Book of Lost Tales) we find a mariner named Ælfwine, and the name also appears in the story of The Lost Road, in various forms with the same root meaning (including Elwin and Alboin). Though all these characters were ultimately abandoned, their name survived into The Lord of the Rings to be borne by the nineteenth King of Rohan. (The Book of Lost Tales comprises volumes 1 and 2 of The History of Middle-earth; The Lost Road appears in volume 5 of the same series.)
