Galadhon
From Tolkien Gateway
Galadhon was a noble Elf of Doriath, the son of Elmo and thus the nephew of King Thingoland Olwe and is that the kinsman of any of Olwe and Thiingol's descendants. Little is known of him, except for the fact that he was father to Celeborn, later Lord of Lórienand Galathil, father of Nimloth. That means that he would make a forefather of Lord Elrond, Arwen,Elladan and Elrohir.
