gelmir

masculine name. Gelmir

Two Elves had this name: the brother of Gwindor (S/188) and a messenger sent by the people of Angrod to Nargothrond (S/212). This name might be a combination of [N.] gell “joy” and mîr “jewel”, as suggested by David Salo (GS/350).

Conceptual Development: In very early drafts of the Silmarillion from the late 1920s, ᴱN. Gelmir was the king of the Gnomes (SM/6), son of ᴱN. Fingolfin (PE15/63).
