The name Sienna comes from the Italian town Siena. It also means orange brown, almost a burnt brown colour like the tiles used on the rooftops there. It also means old and wise. I love the name Sienna Rose. It is unique and classy and beautiful for a girl. It is a lot better than Paris, Channel, Scarlott or Mia(h), those are kind of unusual but chavy names and remind me of popular, prissy girls at school. I know a few Sienna's and they are very good natured and well liked. Also very beautiful! Maybe it's all to do with the name!
