Alcyone makes me think of serenity and of the moon. It's one of those names that goes with Irene or Selene. Peaceful. I like to pronounce it Al-See-Own.
Would it be at all permissible to pronounce the name al-SEE-oh-nee instead of al-SYE-oh-nee? Because although it's not the proper way, I much prefer the first one.
