About the Name Siena
Siena descends from the iconic Italian Tuscan city of Siena (Latin Sena Iulia) — one of the iconic Renaissance Italian city-states, founded by the Romans, famous for its iconic Palio horse race held twice yearly in the Piazza del Campo, and known for its iconic medieval architecture and Sienese Gothic art. The Tuscan city has been continuously a UNESCO World Heritage Site since 1995.
The various spellings (Siena, Sienna) are tracked separately by SSA and represent the same underlying Italian place-name. Notable bearers include the iconic British actress Sienna Miller (using the alternate Sienna spelling, born 1981, the iconic British-American actress of American Sniper 2014 and Layer Cake 2004); American basketball player Siena Walker; the contemporary fictional Siena of various contemporary novels.
Siena's American climb is recent: the name climbed from outside the US top 1000 in 2010 to the US top 300 girls' rank by 2018 and the top 300 since. The name has been used predominantly for girls in modern American naming. The name's appeal sits in three contemporary American naming preferences: the in-built Italian-Tuscan-Renaissance place-name register, the popular three-syllable -ena ending family (Siena, Aria, Mia, Sienna), and the modern visual presence. Three flowing syllables, soft consonants, and tonal warmth distinctive to Italian-derived naming. The name reads as both classical-Italian and contemporary American with the strong Sienna Miller cultural anchor (using the related Sienna spelling). Common nicknames Sin (the dominant short form, casual and warm), Sissy, Ena, and the rare Sia each carry distinct registers; the alternate spellings Siena (the simpler Italian spelling), Sienna (the more popular American spelling), and Sianna have their own SSA tracking. International forms include Siena (Italian original) and the original Latin Sena Iulia.
