Meaning & origin

Caston is a rare modern name that first appeared in U.S. birth records in 1919 but has seen only sporadic use. In 2025, only 8 boys were named Caston, a rate of 1 in 113,872 births, placing it at rank 5,861. Its peak year was 2017, when it ranked 4,367th. The name's trajectory has been stable for decades, never achieving widespread popularity. It is most often chosen by parents seeking a distinctive alternative to similar-sounding names like Casten or Cason. Caston has no strong ties to any particular U.S. state, as its usage is scattered. The name's obscurity adds to its appeal for those wanting a truly unique choice.

Caston likely originated as a surname or a variant of the name Casten. It may derive from the Latin 'castus' meaning 'pure,' though this connection is speculative. The name has seen occasional use as a given name in the United States, particularly in the 2010s. Its modern usage likely stems from its phonetic similarity to popular names like Caden or Easton.
