Siena
Meaning
variant of Sienna, the orange-red color word that traces to the Italian city and its clay; the spelling perhaps influenced by the city
The story
Siena is a variant of Sienna, says Behind the Name, with the spelling perhaps influenced by the Italian city, and Sienna is the English word for an orange-red color that itself traces to the city of Siena and the color of its clay. So the name is a color first and a city just underneath, one dropped n keeping the geography closer to the surface. The American records show it arriving with the color wave: about 5 girls each in the 1960s and 1970s, about 700 in the 1990s, about 2,900 in the 2000s, about 4,600 in the 2010s, and about 2,700 so far this decade. Brazil's census counts its first hundred, nearly all recent. A Tuscan hill town, a painter's pigment, and an American nursery name, all sharing one warm shade.
