Burin

Burin, was a Dwarf that Tolkien abandoned while in the process of creating Lord the Rings. Burin first started out as the son of Balin and attended the council of Elrond with Glóin as well as accompanying the Fellowship on their quest. When that idea was abandoned and Gimli was created in his stead, he later had him as the father of Balin, but that was scrapped as well for Fundin.
