Gereth

Gereth was one who aided the flight of Evranin from Artanor (the place which would become Doriath), during the years following the battles between Elves and the Nauglath. They two bore the Necklace of the Dwarves away from the sons of Feanor.

Gereth and Evranin are not mentioned in the final story of the Necklace of the Dwarves in The Silmarillion.
