Origin: Italian

Meaning: From Siena; Orange-red

Sienna, a Latin and Italian girl's name, creates a sense of warmth that baby can strive to emulate. It means "from Siena," a medieval Italian city that's known for its iron-rich clay, the color of which was eventually named after the city. If clay doesn't seem like it'll be quite cool enough for baby, then look to stylish actress Sienna Miller or Sienna Elizabeth, the daughter of Britain's Princess Beatrice. It's perfect if you're looking to add some color to baby's life.
