Our story of Sianna
Our story of Sianna is a story of a Welsh name lengthened. Siân is the Welsh Jane, descending through Norman Jehanne from the Hebrew for 'the Lord is gracious' — one of the most-traveled names in European history. American families added an -na ending in the 2000s, producing Sianna alongside Siena, Sienna and Shianne. The Welsh half has three thousand years behind it; the ending has twenty.
Meaningscholars disagree
God is gracious
The Sian- front is likely the Welsh Siân, a form of Jane from the Hebrew Yochanan, 'the Lord is gracious'. The -na ending is a modern addition. Alternatively it is a modern coinage on the sound. The Welsh route gives a documented meaning; the compound is new.

- counting every spelling
The SSA counts spellings, not names. Sianna went to 87 girls in 2025, but Cianna, Siana and Ciana and the rest below are the same name said out loud. Together the 8 spellings went to 296, which makes it the 674th most-given girls’ name of the year — 1,465 places above the chart.
About 1 girl in 5,430 born in 2025 was given one of these spellings — against 1 in 18,474 for Sianna itself.
Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method

The Shontae test
Every popular name lives one long story — a climb, a peak, a slow settling back. Sianna's later chapters haven't been written yet, so we borrowed them: Shontae climbed just as high around 1985, and its whole arc is on record. Line the two peaks up, and Shontae's path sketches the road Sianna is walking now.
