Which one do you like the best?

Elle Vivienne. Second choice, Elle Margaret. Drop the Suri and the hyphen...both are bad ideas and just make the name too, too much. Seriously, just seeing a nametag with "Elle-Suri" on it as a first name would make me roll my eyes at the pretention. A simple yet elegant and unusual first name like Elle, and a fancy clic middle name like Margaret or Vivienne, is plenty.
