Your doom lies in your name, not in yourself....

[Galorme]

Isn't it every person's wish (or it was a while ago) that their daughter would wed a man of noble birth. Elrond may not have wanted her to wed a King of Men, maybe just an elf of noble blood.

Another thing is that the name could have been given in retrospect, adapted into the stories by men much later (cf the Shivering Falls, or Shuddering Waters, or whatever, the name of the place where Turin and his sister die).
