I was a Smith, I took my husbands Arabic surname. I love it, it means 'Distinguished or Exquisite' in his language. It also means people think I'm Middle Eastern and get a surprise when they see a auburn haired, pale and freckled white woman if they've not seen my first name.
If I could have any name I'd be a Rainbow, I have a friend who is one. I was always jealous when growing up as Smith was sooooo boring when I was a teen.
