Ruan (I know it's Chinese, and I was told it means "musical instrument" but I'm not so sure about that.)
Weisz (I think it means "wheat"... I'm pretty sure it's different from Weiss and/or Weiß, which I already know mean "white.")
Gautier (French. Something to do with lumber?)
Doherty (I was told it was Celtic/Gaelic for obstructive or hurtful, but that doesn't sound right....)
Thanks in advance.
