Origin, sound and short forms
Our story of Caison
Our story of Caison is a story of an ending that stopped meaning anything. The -son suffix in Jackson, Hudson and Mason is a genuine patronymic — somebody's son — and American naming detached it in the 2000s and used it as a decoration: Caison, Jaxon, Braxon, Kason. A Cason surname exists in England and its origin is not recovered. Caison appears in the registers in the 2010s, and no source gives it a meaning.

Not established

- counting every spelling
The SSA counts spellings, not names. Caison went to 60 boys in 2025, but Kayson, Kaison and Cayson are the same name said out loud. Together the 6 spellings went to 2,229, which makes it the 172nd most-given boys’ name of the year — 2,132 places above the chart.
and 2 rarer spellings.
About 1 boy in 766 born in 2025 was given one of these spellings — against 1 in 28,468 for Caison 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 Cordarro test
