Sienna has been a Top 100 choice in England & Wales since 2005, the year after Sienna Miller's acting breakthrough in the hit movies Alfie and Layer Cake. In the US, it also got a big boost in the early noughties, before dropping slightly then rebounding to reach an all-time high in 2022.

 Now the name Sienna has gotten maybe its biggest boost of all when it was announced as the name of the daughter of Princess Beatrice and Edoardo Mapelli Mozzi. The royal baby, born in 2021, is named Sienna Elizabeth. Cable newsperson Campbell Brown also chose Sienna for her daughter, as did Kevin James. 
 
The historic Tuscan city is spelled Siena, but the Sienna spelling is the one used recently by Princess Beatrice for her daughter. Sienna, also the spelling used by American-born English actress Miller, is more popular than Siena in the English-speaking world. 


 The city of Siena is said to have been founded by Senius and Aschius, two sons of Remus. The name of the city may derive from Senius, although other possibilities include Roman or Etruscan family names, a Gaulish tribe name, or a Latin root meaning "old". 

 The English color word "sienna" ultimately comes from the name of the iron-rich clay in the Italian city, brownish yellow when raw and reddish brown when burnt, making this a vibrant color name as well as a romantic place name.
