This character was first mentioned as Frár, who attended the Council of Elrond with Glóin. He was changed to Burin the son of Balin, that later would join the Fellowship on their quest. When that idea was abandoned and Gimli was created in his stead, the name was used for the father of Balin, but that was scrapped in favour of Fundin.
